Well, I think it's the same as you'd do anything in Python -- not
everything has to be a servlet, and you don't have to use the logic flow
that's built into Webware. In fact, you aren't expected to use it --
you are expected to make your own logic.
For instance, if you want to sort on a field, you might have links like:
self.write('''
<table>
<th><a href="?sort=name>Name</a></th>
<th><a href="?sort=age>Age</a></th>
''')
dbresults.sort(lambda a, b, field=self.request.field('sort', 'name'):
cmp(a[field], b[field]))
# Then you write the results
You can use the self.response().forwardRequest('newServletName') if you
want to go to another servlet completely. But otherwise, it's simply a
matter of normal Python -- you call functions and methods, test values,
etc. If you want to pass control over to another method in the same
servlet, just call that method (self.newMethod()).
