Redmine

I need to setup Redmine and integrate the content of this server on another server with ProxyPass directive. On both hosts we have an apache2 webserver.

Redmine Host (CentOS 6 with Phusion Passenger):
from httpd.conf:

<VirtualHost redmine.internalhost:80>
    ServerAdmin webmaster@company.com 
    DocumentRoot /var/www/redmine/public 
    ServerName redmine.internalhost
    ErrorLog logs/redmine_error_log
    <Directory /var/www/redmine/public>
        Options Indexes ExecCGI FollowSymLinks -MultiViews
        Order allow,deny
        Allow from all
        AllowOverride all
    </Directory>
</VirtualHost>

When I connect to the redmine.internalhost on Port 80 directly without the proxy in the middle, I get the redmine page as expected, I can login and everything works fine.

So I tried to map redmine into some other page on a proxyhost with Location /redmine:

httpd.conf from the proxyhost (CentOS 5.5):

ProxyPass               /redmine http://redmine.internalhost     # of course this is not the real URL, but the one that works
ProxyPassReverse        /redmine http://redmine.internalhost

<Location /redmine>
        Options Indexes ExecCGI FollowSymLinks -MultiViews 
        Order Allow,Deny
        Allow from all
</Location>

So when I try to access redmine via the proxyhost (tested both over https and https, even though the page needs to be accessible over https in the final configuration like https://somehost.com/redmine), the page shows up without CSS loaded and with all the links broken. Following a link leads to a "THE PAGE YOU REQUESTED CANNOT BE FOUND"-error.

Help appreciated. Any ideas are welcome.

Thanks
