Digest authentication is performed in the headers of requests and 
responses.  The server sends a challenge, the client computes a response 
proving they know a secret only one user is supposed to know.

The response object has all of the headers sent from the server.  You 
can inspect them and then compute the appropriate challenge response to 
include in your *next* request.  If you get it right, then the server 
will give you the content instead of sending you a challenge.

Some work has been done on adding higher-level support for this feature 
to Twisted, but it is not yet complete.  You can follow its progress or 
pitch in at <http://twistedmatrix.com/trac/ticket/5148>.
