question about writing threaded web server

I'm trying to teach myself threads and sockets in C and decided the best way was to write a multithreaded http server. I'm having a little bit of trouble putting together the pieces, can someone more knowledgeable than myself tell me whether I have the right idea?

I've figured out how to open and bind a socket. Here's what I'm trying to do after that:


int main() {

    // set up connection
    ...
    // already listening, socket connection var is sfd
    while(connfd = accept(sfd, NULL, NULL)
    {
        if(connfd < 0)
         // scream and die

        pthread_create( [ vars, handle thread with serv() ] );
    }
}

void* serve(void* args)
{
    /// declare vars used below
    accept( [appropriate args throughs *args] );
    recv( [from connection[ );
    // *request now contains the URL the client asked for
    send( [http 200 or 404, depending] );
    // mutex lock file pointer to log file, to log pages served
    // write to log file
    // mutex unlock log file

    pthread_exit([whatever arg it is]);
}

Is the general idea right?

Why do you wait for two connections before processing one request?
