It sure can. :-) An AJAX request is just a normal request, but initiated
via JavaScript and returning XML or JSON. For example, a web.py handler that
grabs the number of users on your site and returns it as JSON (untested):
class num_users:
def GET(self):
n = web.select('users', what='count(*) as n')[0].n
web.header('Content-Type', 'text/plain')
print '[%d]' % n
DecentURL.com uses an AJAX-style request like this for its live "grabbing
title" feature. See the docs for api-title here:

And here's the AJAX JavaScript that calls this:
