Actually come to think of it you should be able to use POST with
GetFeatureInfo the regular way, but you have to mimic the submitting of a
form. So basically create the body of the request with the key value pairs
and set the Content-type header to "application/x-www-form-urlencoded" and
it should work. Sorry should have thought of that before.
