urllib equivalent for HTTP requests

[K]

Hello everyone,

I understand that urllib and urllib2 serve as really simple page
request libraries. I was wondering if there is a library out there
that can get the HTTP requests for a given page.

Example:
URL: http://www.google.com/test.html

Something like: urllib.urlopen('http://www.google.com/
test.html').files()

Lists HTTP Requests attached to that URL:
=> http://www.google.com/test.html
=> http://www.google.com/css/google.css
=> http://www.google.com/js/js.css

The other fun part is the inclusion of JS within <script> tags, i.e.
the new Google Analytics script
=> http://www.google-analytics.com/ga.js

or css, @imports
=> http://www.google.com/css/import.css

I would like to keep track of that but I realize that py does not have
a JS engine. :( Anyone with ideas on how to track these items or am I
out of luck.

Thanks,
K
