Zimbra and mod_proxy

[clancyian]

I have set up zimbra for my employer on one of our internal servers. I now want employee's to be able to access there email using the zimbra web client. We have a server in our DMZ that used to host squirrelmail to access our old imap server. I would like to use apache and mod_proxy on this server to reverse proxy requests from www.oursite.com/zimbra to the internal zimbra host. I've added the following lines to the apache server in the DMZ to reverse proxy to zim

ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /zimbra http://internal.host
ProxyPassReverse /zimbra http://internal.host

This works! almost. When i enter www.oursite.com/zimbra on my browser i get zimbra's distinctive grey background but not the login form.
On inspection of my httpd error logs in the DMZ i noticed the following error:

File does not exist: /var/www/html/js, referer: http://www.oursite.com/zimbra

Can anyone see what i might be doing wrong ?. Has anyone else a setup similar to the one i am attempting. I'm sure others out there must have attempted this setup.
Thanks
Ian

Welcome to the forums.

Does this page tell you what you need to know?

Yes thank you,
That done the trick. only difference was that my apache was on a different server than Zimbra's.

Mine too, and works very good

I am trying to do just as you did, to no avail. I have a Mac mini running OSX 10.4.9, Apache 1.3
I am using the following settings:
<VirtualHost *:80>
ServerName revproxy.mydomain
ProxyPass /zimbra http://zimbra.mydomain
ProxyPassReverse /zimbra http://zimbra.mydomain
</VirtualHost>
I only get the html, all linked files (css, images,etc) give a 404 error
Am I missing something crucial?
