How do I use proxies with httplib?

[Chad McDaniel]

Proxy configuration with urllib in Python 1.5.1 is broken. If my memory
serves correctly it gives just the error you describe. Upgrade to the
newly-hatched 1.5.2 and everything should be peachy.

You can download it from:
http://www.python.org/1.5/

On a completely different note: can anyone out there explain what
1.5.1p1 is?
