I tried something like this originally, and it solves some of the
problems, but not all of them.  In fact, I'm pretty sure it only works
for URL rewriting because for every "standard" request REQUEST_URI
equals SCRIPT_NAME + PATH_INFO + QUERY_STRING.  Which ends up not
solving any of the problems mentioned in my previous email. For those
cases, simply removing PATH_INFO and QUERY_STRING results in the exact
same SCRIPT_NAME as was originally used.

The main issue is that the information contained in SCRIPT_NAME and
PATH_INFO (as dictated by CGI/1.1) are not the information actually
needed to process the request.  For file-based scripts (PHP and regular
CGI) it works fine, but for handler-based scripts it breaks down.
SCRIPT_NAME should be the part of the path that "triggered" invoking the
script when it actually contains one component beyond the end of the
path that exists as directories in the filesystem.

You can see how for file-based scripts this is a one-to-one match
(unless you're using Reiser 4 ;-P), but for any handlers that can be
based on an arbitrary directory structure, it doesn't exactly work.

I'll see what happens if I take this discussion up on the Apache and
mod_python mailing lists, because it's not just a Quixote problem.  The
mod_mono people have run into similar problems.
