I'd be interested in seeing any references about this. From what I've read, it seems the intent is to not combine them, but I haven't seen anything explicitly forbidding it. Do you have a source that indicates combining URL parameters in a POST is encouraged, or at least permitted?
"I noticed that in the case of POST handle-request-thread (srv.arc) throws away the GET args."
Which seems to be criticizing what I would consider perfectly valid behavior. I'm not sure why you would want to split your parameters for a POST between the POST parameters and pieces of the URL.
If a change to the source is being suggested, it seems reasonable to determine if it's warranted by the protocol.
