   This module keeps a list of valid methods to be performed on a request object, for
   example GET, HEAD, PUT, POST, DELETE, etc. You can assign which method to be performed
   on the request object directly or you can go through the Access module for higher level
   functions.
   
   This module is implemented by HTMethod.c, and it is a part of the W3C Sample Code
   Library.
