mod_cache not having any effect in Apache 2.2.3

[esolberg]

I'm trying to take advantage of mod_cache, and have the following config settings:

 

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

 

<VirtualHost xxxx:80>

    ....

    CacheRoot "/tmp/httpd_cache"

    CacheEnable disk /

    CacheIgnoreCacheControl On

    CacheIgnoreHeaders Set-Cookie

</VirtualHost>

 

I have created the /tmp/httpd_cache directory with permissions set to 666

 

This is getting parsed and read-- it complains if I use any wrong cache directives so it seems to be valid config syntax.

 

However, there are no files at all being written to the cache directory-- no static or dynamic content.

 

Anyone know what I am missing to get mod_cache working?

 

Thanks,

Eric
