Getting PHP to handle other HTTP methods

Hi, I want to get PHP to handle the HTTP methods PROPFIND, PUT, DELETE, MKCOL, RENAME, MOVE, and COPY. I've coded up a WebDAV server in PHP to do things that mod_dav cannot (store content in a database or filesystem, call event handlers, filtering the file list, more sophisticated permission configuration on new folders and files) Currently it's running as a standalone app, using xinetd, but I want to try and get it to run within apache so that I can use the same port, and for efficiency and security reasons. I figured that if I have rewrite rule that changed /dav/(anything) into /dav/mydav.php?uri=(anything) I would be on my way. However, seems to only sends the GET and POST methods to the script. I'm using mod_php, not the standalone w/ a handler. Is is possible to send the extra WebDAV methods to the PHP script? Thanks, Sam
