• Help converting code using httlib2 to use urllib2

  - by ThinkCode

  What am I trying to do? Visit a site, retrieve cookie, visit the next page by sending in the cookie info. It all works but httplib2 is giving me one too many problems with socks proxy on one site. http = httplib2.Http() main_url = 'http://mywebsite.com/get.aspx?id='+ id +'&rows=25' response, content = http.request(main_url, 'GET', headers=headers) main_cookie = response['set-cookie'] referer = 'http://google.com' headers = {'Content-type': 'application/x-www-form-urlencoded', 'Cookie': main_cookie, 'User-Agent' : USER_AGENT, 'Referer' : referer} How to do the same exact thing using urllib2 (cookie retrieving, passing to the next page on the same site)? Thank you.

• Apache or Nginx for php behind Varnish

  - by Macindy

  We are managing a heavy traffic php site (driven with vbulletin). To get less load I use the cache-proxy varnish. Works very well - with varnish the load was reduced by 50%. But now I am thinking about which webserver to use behind varnish. 90% requests getting to the webserver are php-requests. So is there a difference between apache/mpm-prefork with mod_php and nginx/php-fpm? Is apache perhaps better, because it doesn't have the tcp overhead? Thanks for reply - benchmarks would be great! macindy

• NHibernate WCF Bidirectional and Lazy loading

  - by ChrisKolenko

  Hi everyone, I'm just looking for some direction when it comes to NHibernate and WCF. At the moment i have a many to one association between a person and address. The first problem. I have to eager load the list of addresses so it doesn't generate a lazy loaded proxy. Is there a way to disable lazy loading completely? I never want to see it generated. The second problem. The bidirectional association between my poco's is killing my standard serialization. What's the best way forward. Should I remove the Thanks for all your help

• Recording object method calls to generate automated test.

  - by Constantin

  I have an object with large interface and I would like to record all its method calls done during a user session. Ideally this sequence of calls would be available as source code: myobj.MethodA(42); myobj.MethodB("spam", false); ... I would then convert this code to a test case to have a kind of automated smoke/load test. WCF Load Test can do this for WCF services and CodedUI test recorder can do this for UIs. What are my options for a POCO class? I am in position to edit application code and replace the object in question with some recording/forwarding proxy.

• How to read and set a value of a specific cell in an ExtJS Grid ?

  - by Lou

  Hello, I am beginning with ExtJS. I am trying to read a value from a cell that is selected I use an EditorGrid and the store looking like that : my_store = new Ext.data.JsonStore({ root: 'topics', totalProperty: 'totalCount', idProperty: 'details_id', fields: [ {name : 'index', type : 'int'}, {name : 'inactive', type : 'int'}, {name : 'c_1', type : 'string'}, {name : 'c_2', type : 'string'}, {name : 'c_3', type : 'string'}, {name : 'c_4', type : 'string'} ], proxy: new Ext.data.ScriptTagProxy({ url: 'my_proxy_url' }) }); As of now, this is what I use to retrieve the rows and columns of the selected cell : var column = grid.getSelectionModel().selection.cell[0]; var row = grid.getSelectionModel().selection.cell[1]; How can I read the value of a selected cell in the grid and change this value ?

• Popup Dialog Box Manager using PureMVC

  - by webwise

  I am developing a a game in Flash using the PureMVC framework. From time to time I need to show dialog pop-up window to get a user response back (e.g. "Cancel", "OK" and other kinds of asynchronous user feedback) while "locking" the background for interactivity. I need some management for my pop-ups: all pop-up notifications should be stacked up, so that if two (or more) pop-up messages are initiated at the same time I show them one by one. What's the best practice here? Should I employ a proxy to manage my pop-ups (sounds unreasonable). How do I get feedback back from my dialog? using notifications?

• java.io.FileNotFoundException for valid URL

  - by Alexei

  Hello. I use library rome.dev.java.net to fetch RSS. Code is URL feedUrl = new URL("http://planet.rubyonrails.ru/xml/rss"); SyndFeedInput input = new SyndFeedInput(); SyndFeed feed = input.build(new XmlReader(feedUrl)); You can check that http://planet.rubyonrails.ru/xml/rss is valid URL and the page is shown in browser.

• Use boost date_time to parse and create HTTP-dates

  - by John Price

  I'm writing a kind of HTTP proxy, so I need to be able to do 3 things: Parse an HTTP-date given any of the 3 formats specified in RFC 2616, sec 3.3, Convert a file date-time to an HTTP-date string, and Output the date to a string. For reference, theses are examples of the date-times I need to parse. I will output only the first format: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format I'm pretty sure Boost date_time can do all of this, but I'm having some trouble with number 1. Does anyone already have code to do this? Perhaps I'm not using google proficiently, but I can't find an example of how to do this with boost anywhere. Thanks for any help!

• Aspect Oriented Programming Library/Framework for Actionscript 3?

  - by Tom

  I'm looking for a full featured AOP Library for Actionscript 3. The following projects I noticed so far, but they all seem to have their problems: - http://farmcode.org/page/Sodality.aspx (looks most promising so far, however it requires you to create a whole new class for every AOP "call" I believe, and it forces you to follow quite a lot of restrictions, anyone has experience with it? - http://code.google.com/p/loom-as3/ (this one is discontinued) - http://code.google.com/p/floxy/ (dynamic proxy generation? this isn't really AOP as I know it, right?) - http://code.google.com/p/flemit/ (dynamic byte code generation? this is something AOP needs I think, but not the full featured AOP framework I am looking for) Does anyone know of a better solution? Or does anyone have any experiences with AOP in Actionscript 3? Best regards, Tom

• Android webview cookie problem

  - by Tori

  I have a video link in a web view, on the emulator, I hear the audio and no video is displayed. I think this is an emulator issue. I tried on my Nexus One, when I click the link, it opens a new webview and tries to access the server almost immediately reverts back to the webview and does not show the video. Logcat says: WARN/ResponseProcessCookies(486): Cookie rejected: "BasicClientCookie[version=0,name=GX,domain=mail.google.com,path=/proxy/gmail/mail,expiry=Tue Mar 22 19:55:33 EDT 2011]". Illegal domain attribute "mail.google.com". Domain of origin: "android.clients.google.com" How can I fix this?

• HttpWebRequest timeout in Windows service

  - by googler1

  I am getting a timeout error while starting my Windows service. I am tring to download an XML file from a remote system which causes a timeout during the service OnStart. This is the method I am calling from OnStart: public static StreamReader GetResponseStream() { try { EventLog.WriteEntry("Epo-Service_Retriver", "Trying ...", EventLogEntryType.Information); CookieContainer CC = new CookieContainer(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create( Utils.GetWeeklyPublishedURL()); request.Proxy = null; request.UseDefaultCredentials = true; request.KeepAlive = true; //THIS DOES THE TRICK request.ProtocolVersion = HttpVersion.Version10; // THIS DOES THE TRICK request.CookieContainer = CC; WebResponse response = request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); EventLog.WriteEntry("Epo-Service_Retriver", "Connected to Internet...", EventLogEntryType.SuccessAudit); return reader; } } Is there any possibility to avoid this timeout?

• Function Object in Java .

  - by Tony

  I wanna implement a javascript like method in java , is this possible ? Say , I have a Person class : public class Person { private String name ; private int age ; // constructor ,accessors are omitted } And a list with Person objects: Person p1 = new Person("Jenny",20); Person p2 = new Person("Kate",22); List<Person> pList = Arrays.asList(new Person[] {p1,p2}); I wanna implement a method like this: modList(pList,new Operation (Person p) { incrementAge(Person p) { p.setAge(p.getAge() + 1)}; }); modList receives two params , one is a list , the other is the "Function object", it loops the list ,and apply this function to every element in the list. In functional programming language,this is easy , I don't know how java do this? Maybe could be done through dynamic proxy, does that have a performance trade off?

• Could not find default endpoint element

  - by edosoft

  I've added a proxy to a webservice to a VS2008/.NET 3.5 solution. When constructing the client .NET throws this error: Could not find default endpoint element that references contract 'IMySOAPWebService' in the service model client configuaration section. This might be because no configuaration file was found for your application or because no end point element matching this contract could be found in the client element Searching for this error tells me to use the full namespace in the contract. Here's my app.config with full namespace: <client> <endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService" binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding" contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" /> </client> I'm running XP local (I mention this because a number of Google hits mention win2k3) The app.config is copied to app.exe.config, so that is also not the problem. Any clues?

• Load balancer - how to write one for a custom application?

  - by Poni

  Hi! I've written a simple server application which will run distributed on several machines. My question is how does a network load balancer works, in general? I've heard of round-robin and other algorithms, but what I haven't got answer to is how does the process really goes? In socket terms. The client connects to one of the load balancer machines, asks for a "free-to-connect-to" server and simply connects to it? That's the simpliest way I can think of. .. or, does it use the load balancer as a proxy (that implies that all the NBs must be always connected to the application servers, and data is transferred through them)? It's more of a general question. How would you do this? Thank you all!

• Sending BLOBs in a JSON service,... how?

  - by Marten Sytema

  Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

• ASP.NET AJAX or jQuery (UpdatePanel/ScriptManager or UFrame/jQuery.ajax)

  - by Mark Redman

  Hi, We use the asp.net UpdatePanel and the ScriptManager/ScriptManagerProxy for ajax related functionality; reducing full page refreshes and calling WCF Services respectively. we also use jQuery and plugins for some parts of the UI. We have had some issues with javascript library related conflicts, but have come across some posts indicating that there is a lot more overhead using the UpdatePanel. I have found some limited reference to UFrame: http://www.codeproject.com/KB/aspnet/uframe.aspx www.codeplex.com/uframe Is this a commercially viable replacement for the asp.net UpdatePanel? We use a ScriptManagerProxy to reference WCF services and easily create and use a proxy to call the various WCF service methods. Would using jQuery ajax be a more efficient solution here? We have got this working well on various browsers but now seem to be getting some security related issues (as seen in FF Firebug: Access to restricted URI denied" code: "1012) which seem to have started since using jQuery a lot more. Is it possible/viable to not use ASP.NET Ajax at all?

• Handling OPTIONS request in nginx

  - by ctmiller

  We're using HAProxy as a load balancer at the moment, and it regularly makes requests to the downstream boxes to make sure they're alive using an OPTIONS request: OPTIONS /index.html HTTP/1.0 I'm working with getting nginx set up as a reverse proxy with caching (using ncache). For some reason, nginx is returning a 405 when an OPTIONS request comes in: 192.168.1.10 - - [22/Oct/2008:16:36:21 -0700] "OPTIONS /index.html HTTP/1.0" 405 325 "-" "-" 192.168.1.10 When hitting the downstream webserver directly, I get a proper 200 response. My question is: how to you make nginx pass that response along to HAProxy, or, how can I set the response in the nginx.conf? Thanks!

• Separation of static and dynamic content in Java EE applications

  - by Dan

  We work with IBM products and we typically use IBM Http Servers (read Apache) as a reverse proxy for our application servers. For performance reasons we serve static content (.gif, .jpg, .css, .html etc.) from our http servers, to ease the burden a bit from the application server. So far, we have to distribute files to http server and configure it manually (writing custom scripts at best.) The problem is the effort needed to keep everything in synch, especially when you need to update the app. Does any Java EE product support this “out of the box”? Is there a way to have application server do this automatically, like in cluster configuration for example, where master node is in charge of distributing the application to other nodes and for keeping everything in synch.

• WCF high instance count: anyone knows negative sideffects?

  - by Alex

  Hi there! Did anyone experience or know of negative side effects from having a high service instance count like 60k? Aside from the memory consumption of course. I am planning to increase the threshold for the maximum allowed instance count in our production environments. I am basically sick of severe production incidents just because "something" forgot to close a proxy properly. I plan to go to something like 60k instances which will allow the service to survive using default session timeouts at a call rate average for our clients. Thanks, Alex

• Best Work Queue service for distributed clusters

  - by onewheelgood

  Hi there. I require a simple work queue type system for asynchronous task management. I have looked at both beanstalkd and gearman. However, both these seem to assume that the client and the queue server are on the same network, and therefore that there will always be a reliable network between them. I need one that can support the client and server being in different places in the world, and be able to manage temporary loss of network connection between clusters. Ideally, this would work in such a way where I post a job to a local proxy that attempts to send it to the main queue server. If there is no network connection, it would try again later, however it would not lose the job or delay the client. Any recommendations?

• richfaces keepAlive not working

  - by Jurgen H

  I have a mediaOutput tag which, in its createContent attribute, requires the backing bean to be in a certain state. A list of values, which is filled in an init method, must be available. I therefore added a keepAlive tag for the whole backing bean. I now indeed see the backingBean in stead of some (richfaces) proxy bean, but the filled list is null again. How to make this possible? I checked that the init method was called and that the list is filled in in the init method. <a4j:keepAlive beanName="myBean" /> <a4j:mediaOutput createContent="#{myBean.writeChart}" ... /> The backing bean public class MyBean implements Serializable { public List list; public void init(ActionEvent event) { // call some resource to fill the list list = service.getItems(); } public void writeChart(final OutputStream out, final Object data) throws IOException { // list is null } // getters & setters }
