[Python-Dev] Tracker item: 735515 - urllib to cache 301 redirections?

[O.R.Senthil Kumaran]

Hi,
One of the tracker items: 735515 mentions that urllib should cache 301 and 302
redirections.

urllib / urllib2 should cache the results of 301
(permanent) redirections. This shouldn't break
anything, since it's just an internal optimisation
from one point of view -- but it's also what the
RFC (2616, section 10.3.2, first para) says
SHOULD happen. 

I am trying to understand, what does it mean.
Should the original url be avaiable to the user upon request as urllib
automatically calls the redirect_request and provides the redirected url only?

I am not completely getting what "cache - redirection" implies and what should
be done with the urllib2 module. Any pointers?

Thanks,
