[mod-security-users] Add SCRIPT_NAME to known CGI variables?

[Eli <eli...@ex...>]

I was looking for a CGI variable which contained only the path of the script
called in the URI, minus the DOCUMENT_ROOT.  Apparently both
REQUEST_FILENAME and SCRIPT_FILENAME are the full script path on the server,
and the only CGI variable I can find that would be those, minus the
DOCUMENT_ROOT, is SCRIPT_NAME, but it isn't accepted (1.9RC1 being used).

Is there any reason this CGI variable is not allowed in mod_security?  If so
what is it?  If not, would a patch submitted adding it be accepted (pending
proper coding techniques and testing obviously)?

Eli.
