Your friends answer is very creative, but the answer is much simpler.
Its in the HTTP specification. (Reading the specification can be quite
enlightening.) And there is a reason.
GET and POST are meant for very different things. GET is for making
requests. POSTs are meant for making changes. The philiosphy is that the
user, not the server is in control of what changes are taking place,
therefore a redirect is a GET request.
Or so the theory goes.
