I've never actually done this so caveat emptor.  A glance at rfc2616 tells
me you're going to need to add a "Pragma: no-cache" to the outgoing header.
Add the line:


somewhere before h.endheaders() in the method open_http() of class
URLopener.  Right next to the GET would probably be good.
Good luck,
