It runs beautifully on chrome.... instant loading. googling for the answer has pointed me towards a possible issue with keep alive and the lack of content l...
Is there any way I could get info such as how long did it take to connect to a remote server, time taken to receive the first byte of response, and the time taken to download the whole file? I'm trying to create something like what Pingdom does. ...
On Windows CE, I am currently in a situation where we implement a simplistic web server from scratch. The predominant use of this server will be in a one-to-one USB RNDIS connection. The server is hosted by the managed application running on the device. Therefore, we tightly integrated POST request handling with delivered web pages. Ins...

I need to serve a file on localhost to a certain application which only accepts http URI-s. However, the files are generated on the fly and I would like to avoid writing to disk, so I decided to write a simple HTTP server using QTcpServer. Luckily, I even found a nice tutorial explaining just that. However, I'm not familiar with HTTP res...
Porting an application from my previous development machine (XP) to a new one (w7), and having an issue with WCF. HTTP could not register URL http://+:8001/KolonistenVanCatan/MetaData/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details). Now, the page ...
I have a very simple question. I recently develop this site: http://revenuephilosophy.eu/ and I noticed that when I use the scroll zoom(ctrl+mouse wheel) on other sites it works great but on mine it has a strange behavior with not all of the components scalling as they should. On the css file I used only percentages in order to keep r...
I'm facing this problem with Java. I want to get some HTML informations from a URL. This code was working for so long, but suddenly, it stopped working. When I access this URL using the browser, it opens with no problem. The code: URL site = new URL(this.url); java.net.URLConnection yc = site.openConnection(); BufferedReader in = new ...
I'm looking for some thin layer on top of handling HTTP requests that can easily do routing to different backends, based on the uri / rest verb / actual service location / .... This layer should also handle encoding into whatever the requested format is (xml / json / returning binary data / etc.). The most important point though is to m...
I know that Comet long polling are bad for Web servers because they occupy one thread per connection. So you cannot have a lot of users with persistent connections or your web server will crash. Is this the same with web sockets in HTML 5? How could this solve the resource problem if it occupies one thread too per persistent connection...
We are writing a HTTP based desktop application whose client runs from outside our NAT. We code and test from inside the NAT. The http server sits within our NAT (yes it is bad network design). What would be the best Java method for automatically detecting where the HTTP client is launching from and passing the appropriate server IP (i.e...
Every ajax chat tutorial ends the same. You run a getChatMsg.php or some script every X milliseconds to check for new messages. But not omegle.com they only send you a packet when you really need it not every X milliseconds. For example I run every ajax chat tutorial i setup and sniff the packets I get a flow of getChatMsg or similar ...

So I am doing the request in a very way : httpClient = new HttpClient(new MultiThreadedHttpConnectionManager()); clientParams.setSoTimeout(timeout); HttpMethodBase method = new GetMethod(request.toString()); ...
I'm serving some files locally via HTTP using QTcpSocket. My problem is that only wget downloads the file properly, firefox adds four extra bytes to the end. This is the header I send: HTTP/1.0 200 Ok Content-Length: 382917; Content-Type: application/x-shockwave-flash; Content-Disposition: attachment; filename=file.swf; This i...
Maybe someone here can help me... I wrote a very simple java http client, which sends an xml as post data to a webserver. Now strangely our customer reports that in the postdata there is a trailing ampersand. I have absolutely no clue how that can be if you look at the source code, where I removed every variable... public static void m...
Keep-Alive connection feature in HTTP protocol is meant to reduce TCP connection hits to web server. It should be able to improve web server performance. However, I found that some web servers deliberately disable KeepAlive feature from server side. In my understanding, some reverse proxy, i.e. HAProxy, disables HTTP keep-alive in orde...
I have a drop box which is populated by information from a database. Some of the items have ampersands in them. When the drop box is changed, there is some ajax done, and this includes sending the info from the drop box in a GET. An ampersand in the name of the item from the drop box messes up the URL for the GET. For example, here is a...
If I execute the following Python 3.1 program, I see only � instead of the correct characters in my browser. The file itself is UTF-8 encoded and the same encoding is sent with the response. from wsgiref.simple_server import make_server page = "<html><body>äöü€ßÄÖÜ</body></html>" def application(environ, start_response): start_res...
On IIS 6 how can I allow the PUT operation on a WCF Rest API? Since I don't have the .svc file (I added a route on global.asax to service class) I can't allow the put operation on the .svc extension on IIS 6. ...
I have a very simple class using HttpListener to receive an HTTP POST from a browser via an AJAX request. I've included a demo that highlights this issue: private static void HandleRequest(HttpListenerContext context) { using (var inputStream = context.Request.InputStream) { for (int i = 0; i < context.Request.ContentLen...
