http/1.1 persistent connection issue.

[<vincent.blondel@xxxxxx>]

Hello all,

I am trying to develop a little program that should be able to send
http/1.1 requests.  This is all running fine but I get some problems
with the persistent connection.

I mean I can send one request in my http connection but the second one
does not seem to work properly.

Maybe I made an error in my code, maybe I do not understand something in
http/1.1 ?

Can somebody help me please ? ... many thks.

        printf("%s",buffer);
    }

    shutdown(i32SocketFD, 2);
    close(i32SocketFD);
