hello, i have a problem with a server that have a proxy to a zimbra server. The server is SUSE, and it's receiving any request to http://thisserver/zimbra and proxy to http://zimbraserver/server, but i made the proxy script normal, like any other, but i only get a white page with nothing, it seems that the proxy is not working well, but only with zimbra, i have others proxies running well.

ProxyPass /zimbra/
ProxyPassReverse /zimbra/

so, with this, if access my server from the browser requesting zimbra, i should get the info from zimbra server itself but the proxy is not working, why?

I'll appreciate any help.
