I'm running 6.0.1 OSS and when I change zimbraMailURL from /zimbra to /mail images work fine if I hit the server directly, but if I hit the server via an apache proxy the images don't load.

My proxy config is very simple.

proxypass / http://zmtest2.owfg.com/
proxypassreverse / http://zmtest2.owfg.com/

any ideas?
