Running Zimbra 6.0.4 behind an Apache 2.3 proxy (on Red Hat 5 x64).

The Zimbra webinterface is running on port 8080, but Apache is proxy'ing to to port 443 using a virtual host.

When a user want's the change its own password, the user is redirected to https://servername.url:8080/h/changepass. Somehow, Apache did not redirect port 8080 to port 80.

Could this because of a hard redirection in Zimbra?
