Please keep in mind that **Apache is not a cache server**, it has 
caching attached more like an afterthought to the mod_proxy. If you 
want predictable caching you will need to use real caching software 
such as Squid.

I personally have moved away from Apache even for small websites since 
there are some other issues with Apache caching, such as zero-length 
responses in some cases.
