Hmm, by definition this should, probably be a `POST` but that would make it miserable to easily use and hit from a browser. If it picked up args from the request then i would definitely lean that direction but since it does a read from the settings files, i suppose it's debatable. Then again, if someone wanted to use a replay attack, they could since it's not a `POST` (and i dunno, make us do a lot of file IO?). 

Same argument should probably apply for clearing the cache then, tbh, both with performance implications. We should probably make a decision on this.
