Setting Up Apache as a Forward Proxy with Cahcing
- by Karl
I am trying to set up Apache as a forward proxy with caching, but it does not seem to be working correctly. Getting Apache working as a forward proxy was no problem, but no matter what I do it is not caching anything, to disk or memory. I already checked to make sure nothing is conflicting in the mods_enabled directory with mod_cache (ended up commenting it all out) and also I tried moving all of the caching related fields to the configuration file for mod_cache. In addition I set up logging for caching requests, but nothing is being written to those logs. Below is my Apache config, any help would be greatly appreciated!!
<VIRTUALHOST *:8080>
ProxyRequests On
ProxyVia On

CustomLog "/var/log/apache2/revalidated-requests.log" common env=cache-revalidate
CustomLog "/var/log/apache2/invalidated-requests.log" common env=cache-invalidate
LogFormat "%{cache-status}e ..."
# This path must be the same as the one in /etc/default/apache2

# put this into the configuration for just one virtual host.

Thank you once again!
