• How mod_cache working with "must-revalidate" and "max-age"?

  - by Dmitriy Sosunov

  Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

Is't right? Let's check it:) Within 30 sec, the Google Chrome didn't perform any requests to the origin server to revalidate a request and has return the response from local cache. When max-age is expired, the Google Chrome perform a request to revalidate: GET http://origin.lo/testpage HTTP/1.1 Host: origin.lo Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Accept: application/xml If-None-Match: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 and response: HTTP/1.1 304 Not Modified Cache-Control: must-revalidate, proxy-revalidate, max-age=30 ETag: "7cf651e2-176f-4ac1-808e-0e0c17cfd0a2" Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Sun, 04 Nov 2012 10:16:20 GMT As you can see, all works as expected.

N.B. Apache 2.4.3 Thanks, I would be grateful for any help.

• Unusual request URL in ASP.NET health monitoring event

  - by Troy Hunt

  I’m seeing a rather strange occurrence in the request information section of an ASP.NET health monitoring email I hope someone can shed some light on. This is a publicly facing website which runs on infrastructure at an Indian hosting provider. Health monitoring is notifying us of server errors via automated email but every now and then the requested URL appears as a totally different website. For example: Request information: Request URL: http://www.baidu.com/Default.aspx Request path: /Default.aspx User host address: 221.13.128.175 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE Obviously the site in question is not Baidu and obviously this attribute is not the referrer either; the “Request URL” value is the path which has generated the error. The IP address is located in Beijing (coincidental given the Baidu address?) and in this instance it looks like the SQL server backend was not accessible (I haven't included the entire error message for security's sake). What would cause the request URL attribute to be arbitrarily changed to that of another site? I’ve never seen this occur in a health monitoring event before. Thanks!

If I remove all the configurations related to Richfaces, the application works like charm. Any advice is much appreciated.

• Ruby / Rails - How to aggregate a Query Results in an Array?

  - by AnApprentice

  Hello, I have a large data set that I want to clean up for the user. The data set from the DB looks something like this: ID | project_id | thread_id | action_type |description 1 | 10 | 30 | comment | yada yada yada yada yada 1 | 10 | 30 | comment | xxx 1 | 10 | 30 | comment | yada 313133 1 | 10 | 33 | comment | fdsdfsdfsdfsdfs 1 | 10 | 33 | comment | yada yada yada yada yada 1 | 10 | | attachment | fddgaasddsadasdsadsa 1 | 10 | | attachment | xcvcvxcvxcvxxcvcvxxcv Right now, when I output the above in my view its in the very same order as above, problem is it is very repetitive. For example, for project_id 10 & thread_id 30 you see: 10 - 30 - yada yada yada yada yada 10 - 30 - xxxxx 10 - 30 - yada yada yada yada yada What I would like to learn how to do in ruby, is some how create an array and aggreate descriptions under a project_id and thread_id, so instead the output is: 10 - 30 - yada yada yada yada yada - xxxxx - yada yada yada yada yada Any advice on where to get started? This requirement is new for me so I would appreciate your thoughts on what you're thinking the best way to solve this is.Hopefully this can be done in ruby and not sql, as the activity feed is likely going to grow in event types and complexity. Thanks

• How can I differentiate between the .net WebBrowser component and an actual browser?

  - by Septih

  OK, so we have an online downloads store accessed via our software. Recently we've had requests to allow downloads via normal browsers and it's fairly easy just to slap a download page on. The problem is that it would be confusing to people having two download links, one for the software and one for their web browser, so we want to differentiate between the two and only show the relevant download link. From what I've gathered, the .net WebBrowser component is the same as IE and uses the same User Agent, so we can't use that unless we subclass the WebBrowser in the software to make it use a specific User Agent. It's the more sensible option, but we'd have to roll out another updated version, which is less than ideal. Are there any other ways to tell if someone's accessing a site via the .net component? My only other alternative is to copy the store to a different address with the different download links and send people there. Again this is doable, but not ideal.

• Is there a JSON parser for VB6 / VBA?

  - by Ben McCormack

  I'm trying to consume a web service in VB6. The service (which I control) currently can return a SOAP/XML message or JSON. I'm having a really difficult time figuring out if VB6's SOAP type (version 1) can handle a returned object (as opposed to simple types like string, int, etc.). So far I can't figure out what I need to do to get VB6 to play with returned objects. So I thought I might serialize the response in the web service as a JSON string. Does a JSON parser exist for VB6?

• OpenSSL not listed under PHP modules but shows up in the configure command

  - by Lauren

  PHP 5.2.12 OS X 10.5.8 If I compile PHP from source with the following configure command ./configure --disable-all --with-openssl=shared,/opt/local it succeeds. However, after a make and make install, php -m does not list the openssl module. Based on what I've read, I think it may be due to multiple installs of the openssl library. Installing the latest version of openssl from source and trying to specify the path in the configure command, --with-openssl=/usr/local, always results in the following error: Undefined symbols: "_EVP_CIPHER_CTX_block_size", referenced from: _zif_openssl_seal in openssl.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [sapi/cgi/php-cgi] Error 1 I've tried a few different variations on the path with no luck. Based on http://blog.yimingliu.com/2009/02/24/missing-library-symbols-while-compiling-php-528/, I've also tried editing the Makefile so that MH_BUNDLE_FLAGS comes later in the compilation line. After spending a good portion of the day on this issue, I'm at a loss. Any suggestions?

• JRuby Slick CanvasGameContainer using too much heap memory

  - by Jwosty

  I'm using Java's Slick library (great, by the way) just fine from JRuby. To start a game, I use AppGameContainer which works completely fine and as expected, but if I try to use CanvasGameContainer instead (I want a resizable window and Slick uses an old version of LWJGL that doesn't support this directly) it throws this error: Fri Jun 01 10:22:07 MDT 2012 INFO:Slick Build #274 Error: Your application used more stack memory than the safety cap of 2048K. Specify -J-Xss####k to increase it (#### = cap size in KB). Specify -w for full StackOverflowError stack trace I've tried increasing the heap size until my computer can't allocate any more memory, but to no avail. The CanvasGameContainer uses an awt window to display, which is resizable. Any ideas on why this is happening and/or how to fix this?

• Most wanted feature for C# 4.0 ?

  - by Romain Verdier

  Some blogs on the Internet give us several clues of what C# 4.0 would be made of. I would like to know what do you really want to see in C# 4.0. Here are some related articles: C# 4 tag on Jon Skeet's blog 4 features for C# 4 What do you want in C# 4 Future Focus - I: Dynamic Lookup .NET 4, C# 4 and the DLR Channel 9 also hosts a very interesting video where Anders Hejlsberg and the C# 4.0 design team talk about the upcoming version of the language. I'm particularly excited about dynamic lookup and AST. I hope we would be able to leverage - at some level - the underlying DLR mechanisms from C#-the-static-language. What about you ?

• ClearCase: Versioning at file level

  - by Naveen

  Hi, I have a perculier problem about how to maintain a clearcase project. This project is a xml schema repository where each schema has a version. This repository is common and is used by all the apps in the enterprise. From clearcase prespective the project has a single component. Now the apps can be using different versions of the schema(s). So we are trying to figureout a way to setup the project in such way that a project can have a baseline of what versions of these files are included in a build. The only way we know of how to do this is to create a component for each schema or group of schemas and create a stream for each app to include the components they use. But that would result in too many components. Has anyone dealth with something like this before? We are prepared to restructre the whole project if necessary, so we are open to any idea. Thans for the help.

• MIT vs. BSD vs. Dual License

  - by ryanve

  My understanding is that: MIT-licensed projects can be used/redistributed in BSD-licensed projects. BSD-licensed projects can be used/redistributed in MIT-licensed projects. The MIT and the BSD 2-clause licenses are essentially identical. BSD 3-clause = BSD 2-clause + the "no endorsement" clause Issuing a dual license allows users to choose from those licenses—not be bound to both. If all of the above is correct, then what is the point of using a dual MIT/BSD license? Even if the BSD refers to the 3-clause version, then can't a user legally choose to only abide by the MIT license? It seems that if you really want the "no endorsement" clause to apply then you have to license it as just BSD (not dual). If you don't care about the "no endorsement" clause, then MIT alone is sufficient and MIT/BSD is redundant. Similarly, since the MIT and BSD licenses are both "GPL-compatible" and can be redistributed in GPL-licensed projects, then dual licensing MIT/GPL also seems redundant.

• Windows 7 explorer always crashes, opens small "Personalized Settings" window

  - by Ian Sellar

  My Windows 7 desktop PC, built by me, started acting very weird in the last couple of days. I use it quite often, about half of the time through TeamViewer. Explorer would crash and restart randomly, almost always through TeamViewer. This made me suspect that TeamViewer was the problem but I have reproduced it with and without TeamViewer several times. The only way I can seem to get the problem not to occur is by booting into Safe Mode. I have used CCleaner and Malwarebytes to make sure it wasn't a registry error or malware causing the problem, and I have tried the fix in the seemly related issue here as well every other fix I have found online including removing security updates KB980408 and KB2926765 as well as using "sfc /scannow" and a bunch of other things I can't remember. More recently when I try to start explorer it is popping up a small window that says "Personalized Settings" on the top, but is completely empty and crashes instantly. The only way I can get it to disappear is to kill the explorer.exe process. I wish I could take a screenshot but I can't seem to open paint or even find the exe. I have tried restarting it, I have tried starting it while the personalized settings window was open. I have come up with two lists of processes the first is the list of active processes when I boot into safe mode and explorer seems to work fine. The second is the list of processes that I can narrow it down to in normal boot and still replicate the problem. There is one process that I can't seem to close. NisSrv.exe which is describes as "Microsoft Network Realtime Inspection Service". When I try to close the process NisSrv.exe it says "The operation could not be completed. Access is denied." When I try to close the related service it gives the same message.

• NoSuchMethodError in Java using XStream

  - by Brad Germain

  I'm trying to save a database into a file using XStream and then open it again later using XStream and deserialize it back into the objects it was in previously. The database consists of an arraylist of tables, which consists of an arraylist of a data class where the data class contains an arraylist of objects. I'm basically trying to create an sql compiler. I'm currently getting a java.lang.NoSuchMethodError because of the last line in the load method. Here's what I have: Save Method public void save(Database DB){ File file = new File(DB.getName().toUpperCase() + ".xml"); //Test sample DB.createTable("TBL1(character(a));"); DB.tables.getTable("TBL1").rows.add(new DataList()); DB.tables.getTable("TBL1").rows.getRow(0).add(10); XStream xstream = new XStream(); //Database xstream.alias("Database", Database.class); //Tables xstream.alias("Table", Table.class); //Rows xstream.alias("Row", DataList.class); //Data //xstream.alias("Data", Object.class); //String xml = xstream.toXML(DB); Writer writer = null; try { writer = new FileWriter(file); writer.write(xstream.toXML(DB)); writer.close(); } catch (IOException e) { e.printStackTrace(); } } Load Method public void Load(String dbName){ XStream xstream = new XStream(); BufferedReader br; StringBuffer buff = null; try { br = new BufferedReader(new FileReader(dbName + ".xml")); buff = new StringBuffer(); String line; while((line = br.readLine()) != null){ buff.append(line); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } database = (Database)xstream.fromXML(buff.toString()); }

• Can't submit new object to WCF DataService because of Primary Key constraint

  - by Rob

  I've got a SQL database that uses Guid's for PK's and upon insert, it generates a NewId(). I have an EF data context setup pointing to that database with the primary keys setup with the Entity key:true, Setter:private and StoreGeneratedPattern:Identity because I want the DB to manage the keys and not have code set the PK property. I have an OData (System.Web.Data.Services.DataService) endpoint to access this data (just like: Hanselman did. I have another app that has a service reference to this service. Upon trying to create a new object from this reference (i.e. Product), the ProductId Primary Key is being defaulted to Guid.Empty when doing var serviceEntities = new ServiceEntities(serviceUri); //OData endpoint var product = new Product(); product.Name = "New Product"; serviceEntities.AddToProducts(product); serviceEntities.SaveChanges(); // error happens here When debugging, I look at the Product.ProductId property and it's set to Guid.Empty. When called SaveChanges, I do not want the ProductId field to be sent to the service. The response I get is: Error processing request stream. Property 'ProductId' is a read-only property and cannot be updated. Please make sure that this property is not present in the request payload. Is there a way to do this or what can I do to get this setup correctly and still have the DB generated the keys. Here is the same setup as the Product example above.

• Adding Table Columns to a Group by clause - Ruby on Rails - Postgresql

  - by bgadoci

  I am trying to use Heroku and apparently Postgresql is a lot more strict than SQL for aggregate functions. When I am pushing to Heroku I am getting an error stating the below.

• Using datetime float representation as primary key

  - by devanalyst

  From my experience I have learn that using an surrogate INT data type column as primary key esp. an IDENTITY key column offers better performance than using GUID or char/varchar data type column as primary key. I try to use IDENTITY key as primary key wherever possible. But recently I came across a schema where the tables were horizontally partitioned and were managed via a Partitioned view. So the tables could not have an IDENTITY column since that would make the Partitioned View non updatable. One work around for this was to create a dummy 'keygenerator' table with an identity column to generate IDs for primary key. But this would mean having a 'keygenerator' table for each of the Partitioned View. My next thought was to use float as a primary key. The reason is the following key algorithm that I devised DECLARE @KEY FLOAT SET @KEY = CONVERT(FLOAT,GETDATE())/100000.0 SET @KEY = @EMP_ID + @KEY Heres how it works. CONVERT(FLOAT,GETDATE()) gives float representation of current datetime since internally all datetime are represented by SQL as a float value. CONVERT(FLOAT,GETDATE())/100000.0 converts the float representation into complete decimal value i.e. all digits are pushed to right side of ".". @KEY = @EMP_ID + @KEY adds the Employee ID which is an integer to this decimal value. The logic is that the Employee ID is guaranteed to be unique across sessions since an employee cannot connect to an application more than once at the same time. And for the same employee each time a key will be generated the current datetime will be unique. In all an unique key across all employee sessions and across time. So for Emp Ids 11 and 12, I have key values like 12.40046693321566357, 11.40046693542361111 But my concern whether float data type as primary key offer benefits compared to choosing GUID or char/varchar as primary keys. Also important thing is because of partitioning the float column is going to be part of a composite key.

• When using Data Annotations with MVC, Pro and Cons of using an interface vs. a MetadataType

  - by SkippyFire

  If you read this article on Validation with the Data Annotation Validators, it shows that you can use the MetadataType attribute to add validation attributes to properties on partial classes. You use this when working with ORMs like LINQ to SQL, Entity Framework, or Subsonic. Then you can use the "automagic" client and server side validation. It plays very nicely with MVC. However, a colleague of mine used an interface to accomplish exactly the same result. it looks almost exactly the same, and functionally accomplishes the same thing. So instead of doing this: [MetadataType(typeof(MovieMetaData))] public partial class Movie { } public class MovieMetaData { [Required] public object Title { get; set; } [Required] [StringLength(5)] public object Director { get; set; } [DisplayName("Date Released")] [Required] public object DateReleased { get; set; } } He did this: public partial class Movie :IMovie { } public interface IMovie { [Required] object Title { get; set; } [Required] [StringLength(5)] object Director { get; set; } [DisplayName("Date Released")] [Required] object DateReleased { get; set; } } So my question is, when does this difference actually matter? My thoughts are that interfaces tend to be more "reusable", and that making one for just a single class doesn't make that much sense. You could also argue that you could design your classes and interfaces in a way that allows you to use interfaces on multiple objects, but I feel like that is trying to fit your models into something else, when they should really stand on their own. What do you think?

• How to decode Google spreadsheet's Json respose as a Php Array

  - by Mohammad

  My google Docs Spreadsheet call returns this response in the json format (I only need everything after "rows") please look at the formatted response here : ) I use php's json_decode function to parse the data and use it (Yes, I am awful at php) This code returns NULL, and according to the documentation, NULL is returned "if the json cannot be decoded". $json = file_get_contents($jsonurl); $json_output = json_decode($json); var_dump ($json_output); // Returns NULL Basically, what i want to accomplish is to make a simple array from the first row values of the Json response. like this $array = {'john','John Handcock','[email protected]','2929292','blanc'} You guys are genius, I would appreciate your insight and help on this very much! Answer as "sberry2A" mentions bellow, the response is not valid Json, google offers the Zend Json library for this purpose, tho I decided to parse the tsv-excel version instead :)

• having a test debug app and a released debug app side by side

  - by Tristan

  Yo! When I download my app from the iStore, the latest test version installed to my phone gets over written. Does anyone know how to have two versions of the same app side by side? On a test project, I edited the build settings so that "realease" and "debug" have different product names. This seemed to solve my problem, however when I try this same trick on my actual project, the two overwrite each other again. Does anyone have a recommendation? I don't mind how it's done. Thanks! Tristan

• Spell checker software

  - by Naren

  Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren
