Apache2 mod_proxy, mod_rewrite and mod_cache

Question

I have frontend apache2 and backend tomcat6 with apache lenya.

Proxy works fine but I want to cache images.

Here is my simple config:

ProxyPass / http://192.168.0.82:8888/ ProxyPassReverse / http://192.168.0.82:8888/ RewriteRule ^/$ index.html [R] RewriteRule ^/default/live/(.*)$ $1 [R,L] RewriteRule ^/(.*) http://192.168.0.82:8888/default/live/$1 [P] ProxyRequests Off RewriteEngine On 

and I tried to cache it in this way:

<IfModule mod_disk_cache.c> CacheEnable disk / CacheRoot "/var/cache/mod_proxy" CacheRoot /home/apache2/cache CacheDefaultExpire 60 CacheMaxExpire 3600 </IfModule> 

But I got nothing...

I even tried this way:

<IfModule mod_mem_cache.c> CacheEnable mem / MCacheMaxObjectSize 1024000 MCacheSize 102400 </IfModule> 

again without results.

mod_mem_cache and mod_disk_cache enabled. So I don`t know where the problem is... Could you help me, please?

For starters: you have a double entry for the CacheRoot.
