You can check out my whole conf here :
I'm still wondering how to setup  ServerLimit / MaxClients bigger then 256 *IF* this option

    Server Built: Aug 16 2007 22:41:15
    API Version: 20020903:11
    Hostname/port: intranet.xxxxxxxxx.local:80
    Timeouts: connection: 45    keep-alive: 45
    MPM Name: Prefork
    MPM Information: Max Daemons: 256 Threaded: no Forked: yes
    Server Root: /etc/apache2
    Config File: /etc/apache2/apache2.conf

I think I'm using Prefork, right ?
