And that was the night you learned about this part of RFC 2616 (HTTP
1.1), right? :)

"In particular, the convention has been established that the GET and
HEAD methods SHOULD NOT have the significance of taking an action other
than retrieval...Methods can also have the property of "idempotence" in
that (aside from error or expiration issues) the side-effects of N > 0
identical requests is the same as for a single request. The methods
GET, HEAD, PUT and DELETE share this property."
