Oh, and watch out for a Classic Error I saw in someone's code a little 
while ago..
They had entered a bunch of state-modifying buttons like this:
<a href="/blah/blah/$id/delete" onclick="confirm(..)"><img 
src="/static/trashcan.gif" alt="Delete"/></a>

But what happens when your site gets spidered by a search engine, that 
follows all links?

Whoops.

There's a good reason state-modification-actions should be POST (or 
rather, non-GET, if you want to go with PUT, DELETE, etc)
