• Configuring squid as reverse proxy

  - by Hassan

  I am having trouble configuring squid to work as reverse proxy here is my scenario squid is installed on server with ip 10.1.1.139 I have another computer that is acting as my proxy server 10.1.85.106 which has access to 10.1.85.106/program I want 10.1.1.139/program to be redirected to 10.1.85.106 I have added cache_peer 10.1.85.106 parent 80 0 no-query originserver name=server_1 cache_peer_domain server_1 /program /program/ program when I go to 10.1.1.139/program I get "The following error was encountered while trying to retrieve the URL: /program Invalid URL" Since the error is not related to access denied I don't think it is due to access restrictions. Do I need to add anything else? Thanks for your time

• An open plea to Microsoft to fix the serializers in WCF.

  - by Scott Wojan

  I simply DO NOT understand how Microsoft can be this far along with a tool like WCF and it STILL tout it as being an "Enterprise" tool. For example... The following is a simple xsd schema with a VERY simple data contract that any enterprise would expect an "enterprise system" to be able to handle: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="Sample"     targetNamespace="http://tempuri.org/Sample.xsd"     elementFormDefault="qualified"     xmlns="http://tempuri.org/Sample.xsd"     xmlns:mstns="http://tempuri.org/Sample.xsd"     xmlns:xs="http://www.w3.org/2001/XMLSchema">    <xs:element name="SomeDataElement">     <xs:annotation>       <xs:documentation>This documents the data element. This sure would be nice for consumers to see!</xs:documentation>     </xs:annotation>     <xs:complexType>       <xs:all>         <xs:element name="Description" minOccurs="0">           <xs:simpleType>             <xs:restriction base="xs:string">               <xs:minLength value="0"/>               <xs:maxLength value="255"/>             </xs:restriction>           </xs:simpleType>         </xs:element>       </xs:all>       <xs:attribute name="IPAddress" use="required">         <xs:annotation>           <xs:documentation>Another explanation!  WOW!</xs:documentation>         </xs:annotation>         <xs:simpleType>           <xs:restriction base="xs:string">             <xs:pattern value="(([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])"/>           </xs:restriction>         </xs:simpleType>       </xs:attribute>     </xs:complexType>  </xs:element>   </xs:schema>  An minimal example xml document would be: <?xml version="1.0"encoding="utf-8" ?> <SomeDataElementxmlns="http://tempuri.org/Sample.xsd" IPAddress="1.1.168.10"> </SomeDataElement> With the max example being:  <?xml version="1.0"encoding="utf-8" ?> <SomeDataElementxmlns="http://tempuri.org/Sample.xsd" IPAddress="1.1.168.10">  <Description>ddd</Description> </SomeDataElement> This schema simply CANNOT be exposed by WCF.  Let's list why:  svcutil.exe will not generate classes for you because it can't read an xsd with xs:annotation. Even if you remove the documentation, the DataContractSerializer DOES NOT support attributes so IPAddress would become an element this not meeting the contract xsd.exe could generate classes but it is a very legacy tool, generates legacy code, and you still suffer from the following issues: NONE of the serializers support emitting of the xs:annotation documentation.  You'd think a consumer would really like to have as much documentation as possible! NONE of the serializers support the enforcement of xs:restriction so you can forget about the xs:minLength, xs:maxLength, or xs:pattern enforcement. Microsoft... please, please, please, please look at putting the work into your serializers so that they support the very basics of designing enterprise data contracts!!

• Viewing file: protocol requests made from a swf

  - by Erik Vold

  I've got a swf file in a index.html file, the swf is basically loading images, but it requests a xml file which details where the image/asset files are located. Now the index file (which is just html, js, and css) works (ie: the swf file is working) when used on this url: http://localhost:8500/core/index.html which I'm able to do with Coldfusion 8 single server development environment. But when I access the file directly with this url: file:///C:/ColdFusion8/wwwroot/core/index.html the swf file does not work. So I'm guessing that the swf is having trouble locating the files that it needs. The problem is I have no idea what file urls it is try to access atm, and both Firebug and Fiddler are not able to inform me what requests are made on the file: protocol. So is there another tool that I can use?

• Caching factory design

  - by max

  I have a factory class XFactory that creates objects of class X. Instances of X are very large, so the main purpose of the factory is to cache them, as transparently to the client code as possible. Objects of class X are immutable, so the following code seems reasonable: # module xfactory.py import x class XFactory: _registry = {} def get_x(self, arg1, arg2, use_cache = True): if use_cache: hash_id = hash((arg1, arg2)) if hash_id in _registry: return _registry[hash_id] obj = x.X(arg1, arg2) _registry[hash_id] = obj return obj # module x.py class X: # ... Is it a good pattern? (I know it's not the actual Factory Pattern.) Is there anything I should change? Now, I find that sometimes I want to cache X objects to disk. I'll use pickle for that purpose, and store as values in the _registry the filenames of the pickled objects instead of references to the objects. Of course, _registry itself would have to be stored persistently (perhaps in a pickle file of its own, in a text file, in a database, or simply by giving pickle files the filenames that contain hash_id). Except now the validity of the cached object depends not only on the parameters passed to get_x(), but also on the version of the code that created these objects. Strictly speaking, even a memory-cached object could become invalid if someone modifies x.py or any of its dependencies, and reloads it while the program is running. So far I ignored this danger since it seems unlikely for my application. But I certainly cannot ignore it when my objects are cached to persistent storage. What can I do? I suppose I could make the hash_id more robust by calculating hash of a tuple that contains arguments arg1 and arg2, as well as the filename and last modified date for x.py and every module and data file that it (recursively) depends on. To help delete cache files that won't ever be useful again, I'd add to the _registry the unhashed representation of the modified dates for each record. But even this solution isn't 100% safe since theoretically someone might load a module dynamically, and I wouldn't know about it from statically analyzing the source code. If I go all out and assume every file in the project is a dependency, the mechanism will still break if some module grabs data from an external website, etc.). In addition, the frequency of changes in x.py and its dependencies is quite high, leading to heavy cache invalidation. Thus, I figured I might as well give up some safety, and only invalidate the cache only when there is an obvious mismatch. This means that class X would have a class-level cache validation identifier that should be changed whenever the developer believes a change happened that should invalidate the cache. (With multiple developers, a separate invalidation identifier is required for each.) This identifier is hashed along with arg1 and arg2 and becomes part of the hash keys stored in _registry. Since developers may forget to update the validation identifier or not realize that they invalidated existing cache, it would seem better to add another validation mechanism: class X can have a method that returns all the known "traits" of X. For instance, if X is a table, I might add the names of all the columns. The hash calculation will include the traits as well. I can write this code, but I am afraid that I'm missing something important; and I'm also wondering if perhaps there's a framework or package that can do all of this stuff already. Ideally, I'd like to combine in-memory and disk-based caching.

• IIS 6 on x64 and long URLs

  - by mausch

  I have a very long URL on a site hosted on Windows 2003 x64 that looks like this: http://myhost/a_very_very_long_url_around_300_chars_long (i.e. a single, very long segment around 300 chars long) Problem is, I'm getting a 400 Bad Request response from HTTP.SYS (it doesn't even reach IIS). I can tell because these requests show up in system32\LogFiles\HTTPERR, e.g: 2009-09-17 19:51:29 200.123.179.9 3636 192.168.129.50 80 HTTP/1.1 GET /a_very_very_long_url_around_300_chars_long 400 - URL - I tried setting UrlSegmentMaxLength in the registry and this fixes the issue on my Windows 2003 x86 box but not on the x64 production server. I tried this on another Win2k3 x64 server and it also failed. Any hints?

• Why would a FaceBook application "work" on a profile, but not a page?

  - by edt

  I made a FaceBook application that works fine on profiles, but I can't figure out how to get it to show on a FaceBook page. For example, after I visit the application canvas URL, allow the application, then edit application settings and "add" to box and tab view... I cannot click the "plus" symbol to the left of the tabs in order to add a tab for the application. It does not appear in the list of available applications. Meanwhile, the application is working/showing up on profiles with no issues. I DID check the "Installable to Pages" checkbox on the application (authentication tab) settings. What could cause this? Here is the application canvas URL: http://apps.facebook.com/russian_girls/

• How to block spam site republishing my content

  - by Fo.

  I noticed today that Google search results shows some spam copies of one of my sites. The url looks something like this: http://[subdomain].spamsite.com/www.example.com ...where example.com is my site. In my Apache access logs I'm noticing several lines like the following whenever I load the above url: 127.0.0.1 - - [219/Oct/2012:19:27:34 +0000] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)" The spammer's site shows an exact up to date copy of my site, so I think they are pulling in live data. Any idea how I can block this traffic?

• Is it possible to use WebMatrix with pure IIS?

  - by Mike Christensen

  I'd like to check out WebMatrix for publishing our site to IIS automatically (right now, I have to zip it up, copy it out, Remote Desktop into the server, unzip it, etc). However, every example I can find on how to setup WebMatrix involves Azure, or using a .publishsettings file that you'd get from your hosting provider. I'm curious if I can publish to a normal, every day IIS server running on Windows Server 2008. So far, all I've done to the IIS server is install Web Deploy, which I believe is the protocol that WebMatrix uses to publish. When I enter the Remote Site Settings screen, I select Enter settings. I select Web Deploy as the protocol, type in my NT domain credentials (I'm an Admin on that server). I put in the site URL for the Site Name and Destination URL. When I click Validate Connection, I get: Am I doing something wrong, or is this just not possible to do?

• Configure IIS 6 to deny access to specific file based upon IP address

  - by victorferreira

  Hello guys, We are using IIS 6 as our webserver. And we need to deny the access for one specif file, placed in only one specific URL, to everybody OUTSIDE the local network. In other words, if somebody is trying to access that filme/page from their own computer at home, using the internet, they must not succeed. But, if the same person try to do that at the same network of the web server, its ok. I am not sure about that, but Apache uses ORDER DENY,ALLOW. You specify the URL, allow or deny to all or to a range of IP. Any suggestions? Thanks!

• Cookie access within a HTTP Class

  - by James Jeffery

  I have a HTTP class that has a Get, and Post, method. It's a simple class I created to encapsulate Post and Get requests so I don't have to repeat the get/post code throughout the application. In C#: class HTTP { private CookieContainer cookieJar; private String userAgent = "..."; public HTTP() { this.cookieJar = new CookieContainer(); } public String get(String url) { // Make get request. Return the JSON } public String post(String url, String postData) { // Make post request. Return the JSON } } I've made the CookieJar a property because I want to preserve the cookie values throughout the session. If the user is logged into Twitter with my application, each request I make (be it get or post) I want to use the cookies so they remain logged in. That's the basics of it anyway. But, I don't want to return a string in all instances. Sometimes I may want the cookie, or a header value, or something else from the request. Ideally I'd like to be able to do this in my code: Cookie cookie = http.get("http://google.com").cookie("g_user"); String g_user = cookie.value; or String source = http.get("http://google.com").body; My question - To do this, would I need to have a Get class, and a Post class, that are included within the HTTP class and are accessible via accessors? Within the Get and Post class I would then have the Cookie method, and the body property, and whatever else is needed. Should I also use an interface, or create a Request class and have Post and Get extend it so that common methods and properties are available to both classes? Or, am I thinking totally wrong?

• Should I, and how do I incorporate microdata into my asp.net website with 47 pages?

  - by Jason Weber

  I have an asp.net (vb) with 47 pages. The problem is that it's in 10 different languages, although 98% just use English. I have 5 master pages. I've read Google Webmaster Tools, but I'm still confounded. I'm reading about how microdata is the way to go. Does this mean I should put itemtype and itemprop span and div tags in my master pages, or should I do all of my 47 pages (.resx resource files) separately? The main key phrase I want throughout search results is "machine vision". For instance, the first couple sentences on my "about.aspx" page are: <span itemprop="name">USS Vision Inc.</span> (USS) is a privately-owned company with headquarters in <span itemprop="locality">Detroit, Michigan, USA</span>. We design, engineer, produce, and integrate special machine vision error-proofing products and <a href="http://www.ussvision.com/services/" target="_self" itemprop="url">services</a> that create lean factories by improving the quality of manufactured products, and by significantly reducing manufacturing costs through advanced automation. Am I doing this right, or how would I do this if I'm not? Should I use the itemprop="url" or other rich snippets for every link in my website? I mean, do I need to add an itemprop to just about everything, or can I just alter my master pages? Any guidance in this regard to help improve my SEO and SERPS would be greatly appreciated!

• Meta refresh tag not working in (my) firefox?

  - by mplungjan

  Code like on this page does not work in (my) Firefox 3.6 and also not in Fx4 (WinXPsp3) Works in IE8, Safari 5, Opera 11, Mozilla 1.7, Chrome 9 <meta http-equiv=refresh content="12; URL=meta2.htm"> <meta http-equiv="refresh" content="1; URL=http://fully_qualified_url.com/page2.html"> are completely ignored Not that I use such back-button killing things, but a LOT of sites do, possibly including my linux apache it seems when it wants to show a 503 error page... If I firebug or look at generated content, I do not see the refresh tag changed in any way so I am really curious what kind of plugin/addon could block me which is why I googled (in vain) for a known bug... In about:config I have accessibility.blockautorefresh; false so that is not it. I ran in safe mode and OH MY GOD, STACKEXCHANGE IS FULL OF ADS but no redirect

• once VPNed into pfSense, unable to hit the public URLs of my websites - they are routed to the pfSense box

  - by Sean

  I have a pfSense box setup as the firewall/router/VPN appliance at my colo. Once I VPN into the colo (either pptp or openvpn, pptp preferred due to multiple clients and ease of configuration), I am able to hit all my servers by their private 10.10.10.x ip and am able to browse the public internet without issue. When I try and hit the URL of a domain hosted by one of my servers, I am prompted for credentials. If I login using the pfSense credentials, I'm connected to pfSense as if I'd used it's internal IP. If I hack my hosts file to point url - server private IP it works fine, but this is obviously not a good solution. To recap: not connected to VPN - www.myurl.com works connected to VPN - www.myurl.com never makes it to the correct server, but is sent only to the pfSense box I'm sure it's something small that I've missed in the pfSense config.

• Script to check a shared Exchange calendar and then email detail

  - by SJN

  We're running Server and Exchange 2003 here. There's a shared calendar which HR keep up-to-date detailing staff who are on leave. I'm looking for a VB Script (or alternate) which will extract the "appointment" titles of each item for the current day and then email the detail to a mail group, in doing so notifying the group with regard to which staff are on leave for the day. The resulting email body should be: Staff on leave today: Mike Davis James Stead @Paul Robichaux - ADO is the way I went for this in the end, here are the key component for those interested: Dim Rs, Conn, Url, Username, Password, Recipient Set Rs = CreateObject("ADODB.Recordset") Set Conn = CreateObject("ADODB.Connection") 'Configurable variables Username = "Domain\username" ' AD domain\username Password = "password" ' AD password Url = "file://./backofficestorage/domain.com/MBX/username/Calendar" 'path to user's mailbox and folder Recipient = "[email protected]" Conn.Provider = "ExOLEDB.DataSource" Conn.Open Url, Username, Password Set Rs.ActiveConnection = Conn Rs.Source = "SELECT ""DAV:href"", " & _ " ""urn:schemas:httpmail:subject"", " & _ " ""urn:schemas:calendar:dtstart"", " & _ " ""urn:schemas:calendar:dtend"" " & _ "FROM scope('shallow traversal of """"') " Rs.Open Rs.MoveFirst strOutput = "" Do Until Rs.EOF If DateDiff("s", Rs.Fields("urn:schemas:calendar:dtstart"), date) >= 0 And DateDiff("s", Rs.Fields("urn:schemas:calendar:dtend"), date) < 0 Then strOutput = strOutput & "<p><font size='2' color='black' face='verdana'><b>" & Rs.Fields("urn:schemas:httpmail:subject") & "</b><br />" & vbCrLf strOutput = strOutput & "<b>From: </b>" & Rs.Fields("urn:schemas:calendar:dtstart") & vbCrLf strOutput = strOutput & "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<b>To: </b>" & Rs.Fields("urn:schemas:calendar:dtend") & "<br /><br />" & vbCrLf End If Rs.MoveNext Loop Conn.Close Set Conn = Nothing Set Rec = Nothing After that, you can do what you like with srtOutput, I happened to use CDO to send an email: Set objMessage = CreateObject("CDO.Message") objMessage.Subject = "Subject" objMessage.From = "[email protected]" objMessage.To = Recipient objMessage.HTMLBody = strOutput objMessage.Send S

• wildcard in httpd conf file?

  Here is an example httpd config I'm currently using: <VirtualHost 123.123.123.123:80> ServerName mysite.com ServerAlias www.mysite.com DocumentRoot /home/folder </VirtualHost> I'm wondering, is it possible to have a wildcard for the ServerName & ServerAlias variable? Reason for asking is I have some software that is shared among multiple URL's all controlled in a CMS and it's kind of a pain to add new domains via ssh everytimee. And before someone points out a security hole, the software does check the current URL before doing any webpages :)

• Is there some standard way to publish a calendar feed?

  - by CMP

  For a web application I am working on, I would like to be able to give the user a single url that they can enter into the calendar application of their choosing to have events from our application show up in their calendar. Most other sites I have seen that do similar things will have a one time download of an .ics file that can be imported. If I have to require my users to download a new file every time the schedule changes, it sort of defeats the purpose of having the feed at all. The calendar can change many many times a day. What I would really like is something like rss where their calendar program can look up a url and automatically see the most recent data. Does anything like this exist? Our main target is mobile devices, so it really should be supported by iCal and google Calendar. Anything else is bonus.

• Want Google to index redirect urls

  - by Dave Goten

  I'm having issues with users who think that Google Search is the address bar. Some of the sites that link to my site use user friendly addresses with 301 redirects to pages that have less friendly URLs. So, for example if I enter www.foo.com/bar it goes to www.bar.com/page.php?some-parameters-and-utm-codes-etc usually this is done by a 301 redirect in order to keep the SEO from foo.com on bar.com and so on, which I believe is standard practice. However, lately there have been more and more people searching www.foo.com/bar instead of going to www.foo.com/bar directly and because the page /bar is nothing more than a redirect it has no SEO that I know of. Things I've thought of but haven't been able to test, because Google takes forever to update :) (and I'm lazy like that), include using Google sitemaps and having them enter their redirects as entries there. (I could see this working if they were the top search entry all the time, and it might appear as a sitelink, but I don't know if that'll make the url itself show up in searches) Using Canonical tags on my pages to the redirects they set up. Which is a nightmare in itself because of the nature of my pages. One week the www.foo.com/bar might go to www.bar.com/pageA.php the next it might goto www.bar.com/pageB.php and having to remember to take the canonical tag off of pageA, so that it doesn't get confused with pageB would be a pain. Using 302 redirects -.- So I guess the question here is, does anyone have any experience or knowledge about this? What should I do to make www.foo.com/bar show up when someone 'searches' for this redirect url?

• WebSVN accept untrusted HTTPS certificate

  I am using websvn with a remote repository. This repository uses https protocol. After having configured websvn I get on the websvn webpage: svn --non-interactive --config-dir /tmp list --xml --username '***' --password '***' 'https://scm.gforge.....' OPTIONS of 'https://scm.gforge.....': Server certificate verification failed: issuer is not trusted I don't know how to indicate to websvn to execute svn command in order to accept and to store the certificate. Does someone knows how to do it? UPDATE: It works! In order to have something which is well organized I have updated the WebSVN config file to relocate the subversion config directory to /etc/subversion which is the default path for debian: $config->setSvnConfigDir('/etc/subversion'); In /etc/subversion/servers I have created a group and associated the certificate to trust: [groups] my_repo = my.repo.url.to.trust [global] ssl-trust-default-ca = true store-plaintext-passwords = no [my_repo] ssl-authority-files = /etc/apache2/ssl/my.repo.url.to.trust.crt

• Patterns for a tree of persistent data with multiple storage options?

  - by Robin Winslow

  I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

E.g. location ~ ^(.*)(preview)(.*)$ Or something aloong those lines?

• Facebook shared links not opening (Redirecting correctly) [on hold]

  - by Hammad

  I have been in a problem and after hours of searching find nothing useful to counter it. I have a website, and that website has RSS feed attached to facebook page. As I post the content to website it also appears on facebook page. But I have people complaining on my page that my posts don't open when they click the link to read the details. Since I am a Chrome user and didn't notice this happening for months. But as I checked it through firefox and Internet Explorer, I found the links shared actually don't open with these browswers. They only work in Chrome, means they are properly redirected in chrome browser and not in firefox and IE. Whenever I click on links of posts on my page through IE or firefox the url does not simply redirect to my website and I get to see nothing as if I am not connecting to Internet. When examining URL I see this: http://www.facebook.com/l.php?u=http%3A%2F%2Fbit.ly%2F112NVO9&h=EAQHDgTUv&s=1 Which shows that facebook is not redirecting the links properly. Moreover I also use link shortening service bit.ly to shorten my shared links. I have checked same problem exists even if I don't shorten my links. And I checked I am not alone, even the tech giant website mashable.com links also don't open in IE and FF from facebook, they only open in Chrome. From mobile phone the links don't open (redirected properly) even in chrome. Can anyone tell me what is the issue? Nothing much is written about it on Internet as no once has faced this problem. P.S: I have checked from different systems, the problem persists.

  - by ultan o'broin

  Introducing the User Interface Text Editor In Oracle Applications Cloud Release 8, there’s an addition to the customization tool set, called the User Interface Text Editor  (UITE). When signed in with an application administrator role, users launch this new editing feature from the Navigator's Tools > Customization > User Interface Text menu option. See how the editor is in there with other customization tools? User Interface Text Editor is launched from the Navigator Customization menu Applications customers need a way to make changes to the text that appears in the UI, without having to initiate an IT project. Business users can now easily change labels on fields, for example. Using a composer and activated sandbox, these users can take advantage of the Oracle Metadata Services (MDS), add a key to a text resource bundle, and then type in their preferred label and its description (as a best practice for further work, I’d recommend always completing that description). Changing a simplified UI field label using Oracle Composer In Release 8, the UITE enables business users to easily change UI text on a much wider basis. As with composers, the UITE requires an activated sandbox where users can make their changes safely, before committing them for others to see. The UITE is used for editing UI text that comes from Oracle ADF resource bundles or from the Message Dictionary (or FND_MESSAGE_% tables, if you’re old enough to remember such things). Functionally, the Message Dictionary is used for the text that appears in business rule-type error, warning or information messages, or as a text source when ADF resource bundles cannot be used. In the UITE, these Message Dictionary texts are referred to as Multi-part Validation Messages.   If the text comes from ADF resource bundles, then it’s categorized as User Interface Text in the UITE. This category refers to the text that appears in embedded help in the UI or in simple error, warning, confirmation, or information messages. The embedded help types used in the application are explained in an Oracle Fusion Applications User Experience (UX) design pattern set. The message types have a UX design pattern set too. Using UITE  The UITE enables users to search and replace text in UI strings using case sensitive options, as well as by type. Users select singular and plural options for text changes, should they apply. Searching and replacing text in the UITE The UITE also provides users with a way to preview and manage changes on an exclusion basis, before committing to the final result. There might, for example, be situations where a phrase or word needs to remain different from how it’s generally used in the application, depending on the context. Previewing replacement text changes. Changes can be excluded where required. Multi-Part Messages The Message Dictionary table architecture has been inherited from Oracle E-Business Suite days. However, there are important differences in the Oracle Applications Cloud version, notably the additional message text components, as explained in the UX Design Patterns. Message Dictionary text has a broad range of uses as indicated, and it can also be reserved for internal application use, for use by PL/SQL and C programs, and so on. Message Dictionary text may even concatenate together at run time, where required. The UITE handles the flexibility of such text architecture by enabling users to drill down on each message and see how it’s constructed in total. That way, users can ensure that any text changes being made are consistent throughout the different message parts. Multi-part (Message Dictionary) message components in the UITE Message Dictionary messages may also use supportability-related numbers, the ones that appear appended to the message text in the application’s UI. However, should you have the requirement to remove these numbers from users' view, the UITE is not the tool for the job. Instead, see my blog about using the Manage Messages UI.

• What's the easiest way to create an HTTP proxy which adds basic authentication to requests?

  - by joshdoe

  I am trying to use a service provided by a server which requires basic HTTP authentication, however the application I am using does not support authentication. What I'd like to do is create a proxy that will enable my auth-less application to connect via the proxy (which will add the authentication information) to the server requiring authentication. I'm sure this can be done, however I'm overwhelmed with the number of proxies out there and couldn't find an answer how to do this. Basically it seems all I want to do is have a proxy serve this URL: http://username:password@remoteserver/path as this URL: http://proxyserver/path I can run it on Linux, but a plus if I can run it Windows as well. Open source or at least free is a must. A big plus is if it's fairly straightforward to setup.

• WCF REST Error Handler

  - by Elton Stoneman

  I’ve put up on GitHub a sample WCF error handler for REST services, which returns proper HTTP status codes in response to service errors.   The code is very simple – a ServiceBehavior implementation which can be specified in config to tag the RestErrorHandler to a service. Any uncaught exceptions will be routed to the error handler, which sets the HTTP status code and description in the response, based on the type of exception.   The sample defines a ClientException which can be thrown in code to indicate a problem with the client’s request, and the response will be a status 400 with a friendly error message:       throw new ClientException("Invalid userId. Must be provided as a positive integer");   - responds:   Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/lastLogin?userId=xyz   Error Status Code: 400, Description: Invalid userId. Must be provided as a positive integer   Any other uncaught exceptions are hidden from the client. The full details are logged with a GUID to identify the error, and the response to the client is a status 500 with a generic message giving them the GUID to follow up on:       var iUserId = 0;     var dbz = 1 / iUserId;   - logs the divide-by-zero error and responds:   Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/dbz     Error Status Code: 500, Description: Something has gone wrong. Please contact our support team with helpdesk ID: C9C5A968-4AEA-48C7-B90A-DEC986F80DA5   The sample demonstrates two techniques for building the response. For client exceptions, a friendly HTML response is sent in the body as well as the status code and description. Personally I prefer not to do that – it doesn’t make sense to get a 400 error and find text/html when you’re expecting application/json, but it’s easy to do if that’s the functionality you want. The other option is to send an empty response, which the sample does with server exceptions.   The obvious extension is to have multiple exceptions representing all the status codes you want to provide, then your code is as simple as throwing the relevant exception – UnauthorizedException, ForbiddenExeption, NotImplementedException etc – anywhere in the stack, and it will be handled nicely.
