Hi Skip,
Added the updated patch and also added patches to test and documentation also.

Did some investigation on Cache redirection and expires for 302. IMHO, it should be handled as a separate feature request (based on the need), as we will have to handle the Cache-Control header values in addition to expires header. This would amount for good amount of change w.r.t the HTTPRedirectHandler itself.

As for the current Tracker item, please verify and if found suitable checkin to the Python trunk.

Thanks,
Senthil
