Hey all,

I've used httpfox to identify the precise headers being sent by
firefox, and then added them to my program using br.addheaders(), as
per the proper mechanize syntax. No dice. (In fact, these headers were
in the program when I ran it successfully from my friend's computer at
his apartment). So I'm pretty sure it's not a header issue.

I'll check and see whether firefox and my system are using a proxy.

Also, based on Martin's comment, I just wanted to make you all aware
that I intend no misuse, but rather am just trying to learn, as I'm a
programming noob. I am not doing anything that I can't do myself from
firefox (ie, I have an account at the school, and am allowed to sign
on with my name and password and look up information in the student
directory). If I do it for more than one student, it just becomes
repetitive, so I thought this was a first modest goal in learning to
do some programming.)

That said, I'm happy to discontinue the attempts, but I'd like to know
how it is that my computer (unless using firefox) is completely
blocked from opening urls from within python. (And how to fix it).

Thanks for the continued help.
