How do I get apache on Rackspace Cloud Sites to serve scripts with extra path info?
===

I'm running a site on Rackspace Cloud Sites (I don't have access to the apache configuration, but I can potentially ask them to change something or enable me to make the changes).

I have a script called feeds.php and I want to put it in the document root so that it will be script called when requests come in for uris like /feeds/news or /feeds/photos.

All of the apache servers that I run on machines I directly control seem to do this by default. When I put that feeds.php on my other apache sites, it works as I intend it. It's not working on Rackspace Cloud Sites though. I've got a ticket open with them, but I'm trying to understand what it causing this functionality so that I can fix it myself in the future (or at least better describe to Rackspace support what I need).

I've grepped through all of my Apache configs on the server where this is working and I don't have any RewriteRules or anything that would do this. 

Do you know what configuration options make Apache server urls in this fasion?
