Here's what I'm currently doing:
In httpd.conf:
RewriteMap rewriter prg:/usr/local/bin/rewriter.php
In vhosts .htaccess file:
RewriteEngine On
RewriteRule .* ${rewriter:%{REQUEST_FILENAME}^%{REQUEST_URI}} [L,QSA]
I have to "pass" in the both of these so I can find the docroot for
the vhost then find the map file which will always be in the same
location for each vhost.
So far it seems to be doing ok. I was going to add RewriteCond for
checking the the REQUEST_FILENAME actually exists, but I guess that
is an expensive check so I'm having the program handle this too.
If you can get that to work under load, that's great. But I'd worry
about that program becoming a choke point. Only one request at a time
can be processed through the program. (Make sure you are using
RewriteLock to serialize!) So I would do everything possible to keep
requests that don't need the map out of there. That includes doing the
expensive filesystem checks.
