Help please with a URLError. Invoking a url that works in Firefox and
IE results in a "urlerror 7, no address ..." in python. I need to debug
why.
Traceback is below. There's a redirect when the url is invoked (it's
part of a chain) - you can see it using liveheaders in firefox. What is
the best way to debug this? I tried setting debug on HTTPConnection but
this doesn't work (from some web posts, setting debug is broken in
2.4). What's the best way to see what's happening, way to monitor the
call sequences etc?
Any help much appreciated. Thx.
