Why not let some already existing software do the job and only generate an html file?

By creating your own, you are inherently creating security issues so by using one that is already existant, you lessen your problems on the security and coding part.

The server in running on a comp in my friends house althu it is mine comp..

its not suposed to be a real webserver its just so i can type or whatever his ip is in IE

and connect and get a page back giving general info [NONE RISK INFO]
*incase i dint make the point clear: the gameserver is for a game i have made*

+ it is so i can learn this stuff ( i have tryed and failed a lot of times, now i want to see how it can be done ! )

Many existing mud codebases have that built into them. Many of them are open source, so you can take a look there.

I know that you''re not trying to write a mud or anything, but that it is the same concept.

You need to post more info.

Odds are you aren''t properly sending HTTP headers, usually web servers will give an internal error when you don''t send the HTTP header correctly. For you simple page:

Content-type: text/html\r\n\r\n

Here''s what you need to do:

1) create a socket with "socket()" -- it needs to be an INET, STREAM, TCP socket.

2) bind the socket to port 80 on any local address using INADDR_ANY and port 80 (remember htons() !)

3) start listening with listen()

4) select() on the bound socket every so often to see if a connection is coming in

5) if a connection is coming in, call accept() which returns a new socket (the old socket is still listening)

6) read headers and request from this socket using recv(). Note that headers are a number of non-blank lines terminated by a blank line; then the request is a single line.

7) parse the request, and generate the data

8) write headers, followed by a blank line, followed by the response data, using send()

9) close the socket using closesocket() (WinSock) or close() (UNIX)

The headers you have to write in 8 include the status of the request (typically 200 Ok) and the headers "content-type: text/html", "content-length: %d", "cache-control: no-cache" and "connection: close".

For more information on WinSock/sockets, see your local man page or sockets programming tutorial. For more about the HTTP protocol, see the WWWC web page (

Well it crashes when i try to get the request line...

char buffer[256];

ListenSocket(sk, 12);

cli = AcceptSocket(sk, NULL);

if( recv(cli, buffer, 256, 0) < 1)
LError(GTHROW, "Cant get request");

//more stuff down here

and it crashes
when i run the appelication and use IE and connect to

and in my dos window this text appears:

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

so i really dont get why it crashes
