title: How to configure maintenance pages on Passenger suburi deployments
body: <p>I am trying to get a maintenance page setup for a suburi deployment on Phusion Passenger for a rails app.  All the documentation shows DocumentRoot ReWrite rules, which don't appear (don't think they should) rewrite on suburis.  I tried hacking around on the ReWrite rules to point at the suburi, but I can't seem to get it to work.  Has anyone been able to get a setup which works?</p>
