Apache 2.2 cache proxy

Hello,

I need to know if apache 2.2 is able to cache any content that would be
returned from an upstream server (aka Zope in this case). I know how to
do that with a squid server but I have to find a solution with apache
only. I need to configure apache to force a cache of any content without
Zope rendrering cache control headers.

Here's what I started but I can't see any file in my cache directory and
total number of request per second is stable, so I think my
configuration is false but I can not find where.

LoadModule cache_module modules/mod_cache.so
LoadModule disk_cache_module modules/mod_disk_cache.so
LoadModule file_cache_module modules/mod_file_cache.so
LoadModule mem_cache_module modules/mod_mem_cache.so

ProxyRequests On

<Proxy *>
Order deny,allow
Deny from all
Allow from all # For test only
</Proxy>

ProxyVia On

CacheEnable disk /
CacheRoot "/var/cache/mod_proxy"
CacheDirLevels 5
CacheDirLength 3
CacheDefaultExpire 60

<VirtualHost *:80>
ServerName www.monsite.com
DocumentRoot /home/zope/data/www

RewriteEngine on

RewriteCond %{REQUEST_URI} !^/files(.*)
RewriteCond %{REQUEST_URI} !^/common(.*)
RewriteCond %{REQUEST_URI} !^/design(.*)
RewriteCond %{REQUEST_URI} !^/robots.txt
RewriteRule ^/(.*)
http://127.0.0.1:8080/VirtualHostBase/http/%{HTTP_HOST}:%{SERVER_PORT}/Examples/VirtualHostRoot/$1
[L,P]
</VirtualHost>

Any idea ?

Regards,

Laurent

For anybody trying to fix this problem, here is the solution:

Add this directive to your configuration:

CacheIgnoreNoLastMod On
