Apache2.2 vhost template for mongrel clusters

Posted by ezmobius Mon, 12 Jun 2006 06:45:00 GMT

Just wanted to share a template vhost for use with apache2.2/mod_proxy_balancer → mongrel_cluster. This vhost takes care of making apache serve all static and page cached requests while forwarding all dynamic requests to the mongrel_cluster.

Thanks to Bradley Taylor author of mongrel_cluster and owner of RailsMachine.com for this config.
