Hi!

I made a websocket server, but It only works in chrome. I tried to use opera11, FireFox4, Safari5, but with these it dont works. (I re-enabled websockets in FF and Opera) I can connect, but after I sended back the datas, the webbrowser closed the connection (with google chrome, it works)

Try it out here: http://sockettest.fw.hu

In C# I respond to the header with this code:

           string[] headlines = theheader.Split(Convert.ToChar("\n"));

string key1 = "";
string key2 = "";
string origin0 = "";

var key = new byte[8];

foreach (string sor in headlines)
{
    if (sor.Length > 20)
    {
        if (sor.Substring(0, 20) == "Sec-WebSocket-Key1: ")
        {       
            key1 = sor.Substring(20);
        }
        else if (sor.Substring(0, 20) == "Sec-WebSocket-Key2: ")
        {
            key2 = sor.Substring(20);
        }
        else if (sor.Substring(0, 8) == "Origin: ")
        {
            origin0 = sor.Substring(8);
        }
    }
    else if (sor.Length <= 8)
    {
        key = Encoding.Default.GetBytes(sor);
    }
}

var numbersKey1 = Convert.ToInt64(string.Join(null, Regex.Split(key1, "[^\d]")));
var numbersKey2 = Convert.ToInt64(string.Join(null, Regex.Split(key2, "[^\d]")));
var numberSpaces1 = CountSpaces(key1);
var numberSpaces2 = CountSpaces(key2);

var part1 = (int)(numbersKey1 / numberSpaces1);
var part2 = (int)(numbersKey2 / numberSpaces2);

var result = new List<byte>();
result.AddRange(GetBigEndianBytes(part1));
result.AddRange(GetBigEndianBytes(part2));
result.AddRange(key);

using (var md5 = MD5.Create())
{
    string handshake = Encoding.Default.GetString(md5.ComputeHash(result.ToArray()));
    handshake = "HTTP/1.1 101 WebSocket Protocol Handshake\r\nUpgrade: WebSocket\r\nConnection: Upgrade\r\nSec-WebSocket-Origin: " + origin0 + "\r\nSec-WebSocket-Location: ws://" + netip + ":" + port.ToString() + "/\r\nSec-WebSocket-Protocol: *\r\n\r\n" + handshake;
}

So what exactly is your problem? Websockets won't be supported in Firefox until version 6, apparently; I'm not sure about others. Chrome is just ahead, that's all.

You've to understand that it is an early draft:
http://dev.w3.org/html5/websockets/

The layout engines will implement these, Webkit based browsers (i.e. Safari, Chrome) support this better than others (Trident, Gecko)
http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML_5%29#Related_specifications

Feel free to follow individual mail lists or road maps, or keep an eye on that page to view the progress of implementation.
