     The hack here is to check for a dot in the key, but we should find a way
     to catch that in a more sensible way.
     
     One way to check for a valid key would be to check whether the key is a
     valid hostname, but I would like to avoid that for performance reasons.
     
     Addition: we also get queries for various other methods, like "GET" if
