[mod_python] passing a relative URL to handler?

Earlier, I wrote:

I just learned mod_perl request objects have a location() method that returns 
"the path of the <Location> section from which the current Perl*Handler is 
being called." 

http://perl.apache.org/docs/1.0/api/Apache.html#_r_E_gt_location

It'd be useful if mod_python request objects had a similar method...
