Inexplicable Urllib2 problem between virtualenv's when POSTing to a Tomcat server

[Timmy O'Mahony]

Good point.

The two machines that the code works with are running python 2.6.1 and 2.7.2 and are running on my Mac (Snow Leopard)

The two non-working machines are running python 2.6.6 and 2.7.1 and are on Debian 6 and Debian 5 respectively. They are VPSs managed by different providers.

All of the installs are on separate virtuaenvs.
