Re: FastCGI multithread programming problems

Hello,

First of all:

1. Yes you can use many threads
   There are several examples for this technique
   in FastCGI sources.
   
   The main idea: you listen on socket and wait for
   the request. After you "accept" it you get
   ann independent socket you work with it - so
   you have an independent thread to deal with it.

2. There examples in Fcgi sources proposes
   usage of mutex with accept. I think this
   is not the best way to do this.

Nowdays I work on C++ Web Development Framework
that uses FastCGI protocol as a base.
I implemented there a thread pool technique
when the major thread accepts requests and passes
them to worker threads.

You can find and example of such usage
at cppcms.sourceforge.net
Look at
http://cppcms.svn.sourceforge.net/viewvc/cppcms/framework/trunk/

Files thread_pool/worker_thread

Several notes:
1. You should not work with millons of requests
   in same time - server does the job for you.
   You need only create a page
2. Asynchronous technique is quite problematic
   for web development because of 3rd pary API
   that do not support it.

NOTE: I'm not big specialist in FastCGI however
I use it and implemented a framework that is
still on early development stages.
I use thread pool technique and work with
lighttpd web server.
