C# max length of URL

I have a huge problem. I write small servers in C#. My clients are JavaScript. JavaScript use HTTP GET to communicate because JavaScript must pass Same Origin Policy. It means I must use HTTP GET to comunication. Now I notice that C# cut (??) my URL.

I sended:

I lost some important data.

Im listing using:

IPAddress local_ip = Dns.GetHostAddresses(Dns.GetHostName())[0];
TcpListener sockServer = new TcpListener(local_ip,Port);

sockServer.Start();

And

ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadFunction), sockServer.AcceptSocket());

And inside ThreadFunction I have

static void ThreadFunction(Object param)
    {
        Socket socket = (Socket)param;
        proxy.Run(socket);
    }

Finally I read message using this:

int bytes = ReadMessage(socket, readBuf, ref strFromClient);

Can you help me pass problem with URL LENGHT or change method of listining (unknown Javscript clients send large messeage using HTTP GET.)

=================== EDIT

I try using IE, Chrome and FF. I sent

Look

 private Byte[] readBuf = new Byte[2048];
 int bytes = ReadMessage(socket, readBuf, ref strFromClient);

My bytes always are to 1024. Where can be limits of there?

I was careless. Function ReadMessage is function from own class. And it wrote:

sock.Receive(buf, 1024, 0);

Of course I fix:

sock.Receive(buf,buf.Length,0);

And Now it runs. Thank for your answers.

HTTP GET requests are usually limited to ~2000 characters (client-wise, that is)

Here's a reference from MS

GET is not intended for sending large amount of data, that's why it's called GET... try to provide more information regarding your client and we might be able to offer you an alternative
