I try to build something like a web interface for one of my tools. I have
got a problem:

char sendBuf[] = "HTTP/1.1 200 OK\nContent-Type:
text/html\n\n<HTML>\n<BODY>\nHallo\n</BODY>\n</HTML>\n";

I used winsock2 to send - no error in sending, but the browser do not like
to deal with the information in sendBuf[]. Is there something wrong in my
understanding of the HTTProtocoll?

1. Both WinSock and HTTP are off topic in this group.
2. HTTP requires CRLF (\r\n) pairs as line endings, so that's probably your
problem.
3. More info: http://www.ietf.org/rfc/rfc2616.txt?number=2616

I edited answere in definition of HTTP

--code--

strcpy(sendbuf, "HTTP/1.0 200 OK\r\n" );
strcat(sendbuf, "Server: Custom server\r\n");
strcat(sendbuf, "Date: Tuesday, 07-Sep-04 14:47:04 GMT\r\n");
strcat(sendbuf, "Last-modified: Thursday, 07-Sep-04 10:44:53 GMT\r\n");
strcat(sendbuf, "Content-length: 6372\r\n");
strcat(sendbuf, "Content-type: text/html\r\n");
strcat(sendbuf, "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 3.2
Final//EN\">\r\n");
strcat(sendbuf, "<html>Hello</html>");

--/code--

The problem is that when I try to connect to the server though Internet
Explorer, I do't receive the answer from the server. Why?

For more details, I do the next thing:
1. The server runs on my computer, and waits connections
2. In Internet Explorer, I enter localhost-address 127.0.01
3. The server says that there is a client who is connected.
4. The server receives the request from the client.
5. The server sends an answer.
6. ERR: Internet Explorer prints "The page cannot be displayed".

I suppose that it must be an error in formating of my answer...
