Ajax stuff is fun to do, but it's really no different from normal web work, at
least from a C::A perspective. You call run modes just the same. It doesn't
matter how the request makes it to the backend. The only real differences are
the following:

+ you almost never return full pages (header, nav, footer, etc). This is pretty
easy to do with templating. I just set a no_wrapper param that goes to my
templates on Ajax requests to turn off the extra stuff I don't need.

+ JSON - If I have any advice about Ajax programming is don't use XML if you can
avoid it. It's nice to be able to read RSS feeds from some other source, but if
you can control the data source use JSON. It's faster, smaller, easier to read
and more "natural" to Perl. Check out C::A::Plugin::JSON for some easy ways to
use it
