Le module Mod_SSL.

Une bonne présentation^FR des modules mod_cache, mod_disk_cache, mod_mem_cache, mod_file_cache : Guide de la mise en cache.

mod_fcgid is a high performance alternative to mod_cgi or mod_cgid, which starts a sufficient number instances of the CGI program to handle concurrent requests, and these programs remain running to handle further incoming requests. It is favored by the PHP developers, for example, as a preferred alternative to running mod_php in-process, delivering very similar performance.

Rediriger toutes les requêtes

How to redirect an entire server or directory to a single URL ?

The best option is to use the standard Apache module mod_rewrite. If that module is compiled in, the following lines

RewriteEngine On
RewriteRule (.*) http://httpd.apache.org/$1 [R]

will send an HTTP 302 Redirect back to the client, and no matter what they gave in the original URL, they'll be sent to “http://www.apache.org/”.

Voir http://httpd.apache.org/docs/1.3/misc/howto.html#redirect pour tous les détails.

VHost dynamique

Configuration de vhost apache dynamique:

Dynamically Configured Mass Virtual Hosting
Apache Module mod_vhost_alias : This module creates dynamically configured virtual hosts, by allowing the IP address and/or the Host: header of the HTTP request to be used as part of the pathname to determine what files to serve. This allows for easy use of a huge number of virtual hosts with similar configurations.
