The (X)HTML specifications allow both POST and GET as submission methods for forms. Usually it's the former though because of the amount of data to be transferred, and the limitations on the length of a URL (using GET). Often the form will POST, and then the client will be HTTP-redirected using GET to avoid problems with the back button and form re-submission.
