How to grab a part of web page?

[Matthew Sherborne]

Yes you need it already on your disk for that code. I'm not sure how to 
do it with http but it is possible on most servers. You have to send it 
special headers in the request. You can see which headers by reading the 
information in this URL:

http://www.ietf.org/rfc/rfc2616.txt

Search for "partial get" and "range header".

For using httplib in python see this URL:

http://www.python.org/doc/lib/httpconnection-objects.html

Sorry I couldn't be more help. :)
