Instead of going with mod_jk2, I'm trying the mod_proxy method defined here:

I have a <VirtualHost> file set up exactly as the last and it "almost" works, but I'm getting:

403 Forbidden
You don't have permission to access / on this server.

Is there anything I could possibly be forgetting to do? It's set to allow from all, and I haven't specified "/" as a path anywhere. I'm going to attach my vhost config file.
