I’m trying Apache 2 on Ubuntu configured to proxy requests to Mongrel on ports 8000 and 8001. My VirtualHost is configured like this:

<VirtualHost *> … … <Proxy balancer://mongrel_cluster>

BalancerMember [](
BalancerMember [](

RewriteEngine On


RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,:]

When I restart apache I get this error:

Invalid command ‘BalancerMember’, perhaps mispelled…

To enable mod proxy I copied the proxy.load file to mods-enabled, which I though should pull in the neccisary modules. Anyone see something I’m missing?

Upgrade to Apache 2.2 for mod_proxy_balancer.
