I read that we shouldn't use mod_rewrite with Passenger [1] but it seems to
be working OK for me. I noted that the test rails app I generated did not
have a .htaccess file.

My vhost files are below. Is there really anything wrong with using
mod_rewrite this setup? Also, what does RailsAllowModRewrite actually do?
Commenting it out doesn't seem to make a noticable difference.
