Example of using HTTP Auth directly to require authentication before

rendering a page for a client.

This is an example of extremely low-level authentication.  Most applications
7
 
are better served by using L{nevow.guard} instead of manually managing HTTP
8
 
Auth.  See the C{guarded/} example for more information.
