Simle question about HTTP...

How to determine whether the new request header is coming from client in HTTP/1.1 Keep-alive Connections ?

[Mike Nordell]

Looking at the header and check for "Keep-Alive:" ?

How to check whether this is a NEW http-header ? Do I have to check EVERY message or just the first ones?

If your question is instead "How do I know if it's a 1.1 or 1.0" request: Well, read the header. It's all there, in plain-text format. It's either "HTTP/1.0" or "HTTP/1.1". Maybe a trip to this place can clear things up? Especially this page might prove useful.

How can I determine whether the data that was just received, is a HTTP-header? I am writing HTTP proxy server application,it works ok with HTTP/1.0 and fails with HTTP/1.1... For example, when the page contains some data wich needs to be loaded from other server this data is not displayed. I think that browser, when configured to use HTTP/1.1 sends it's requests one after another without breaking the connection. My code looks like: Thread1(started on every connect from client): recv(...); // parse header get URL_to_connect _beginthread(Thread2); // wait here for Event.. while(!Thread1done && !Thread2Done) { recv(...); //from client send(...); //to server } closesocket(); //Thread2 connect(server_ip); // fire the Event... while(!Thread1Done && !Thread2Done) { recv(); //from server send(); //to client } closesocket(); I've read RFC, but found nothing concrete about this...

AFAIK you can't just recv() + send() to pass on any data to any server. You need to parse every request sent from the client to see f.ex. what server to pass on the request to.
