[users@httpd] Help needed on using python script from Apache Rewrite configuration

[Debananda Pal -X (debanapa - WIPRO LIMITED at Cisco)]

Hi,


I have Server version: Apache/2.2.31 (Unix) and trying to pass few arguments 
from Apache rewrite conf file to Python (version 2.6) script.

Also, I want to process the python output in rewrite configuration file.

Please let me know, how can I pass variables to python script and retrieve the 
output in rewrite configuration file.
I have loaded mod_python-3.3.1-16.el6.x86_64 and updated the httpd.conf file 
with proper path.

I have tried below steps just to verify, but no luck :
==========================
RewriteEngine On

RewriteMap d2u "prg:/opt/httpd/custom.d/python_test.py"
RewriteRule .? - [E=vrg:abcd-xyz]?
RewriteRule "-" "${path:%{vrg}e}"
===========================

?Regards,
D Pal
