The 'correct' way to do this is to only generate events on POST HTTP
requests. The HTTP specification dictates that GET must not modify
state, as GET requests may be duplicated or omitted completely by
caching layers.
There's the old story of a CMS with a web front end that used GET to
issue commands. One day a search engine robot found it, and proceeded to
delete all the content in the CMS by traversing the menus.
