I find it curious that REST enthusiasts insist on viewing the world through the five verbs GET, HEAD, PUT, POST, and DELETE. It reminds me of a story:
Back in the early '80s, I worked for DARPA. During the height of the Cold War, we were really worried about being attacked by Russia. My team was charged with designing a RESTful interface to a nuclear launch site; as far as technology goes, we were way ahead of our time.
Anyway, I wanted the interface to be "PUT /bomb". However, my co-worker insisted that it should be "DELETE /russia". One of my other buddies suggested that we compromise on something more mainstream like "POST /russia/bomb".
Finally, my boss put an end to the whole fiasco. He argued that any strike against the USSR would necessarily be in retaliation to an attack from them. Hence, he suggested that it be "GET /even", so that's what we went with.
You have to understand, back then, GETs with side effects weren't yet considered harmful.
