Not on WSGI programming as such, as there is enough of that out there
by other people. For some pointers see:


For mod_wsgi specific material see:


You just need to work out what WSGI capable framework you might want
to use. One lightweight option is web.py if you need to be doing a lot
of customised pages and request handlers. For a more structure system
have a look at Django. In between you have Pylons, which aims to be a
more componentised system where you can mix and match stuff.
