- An interface specific to the HTTP verb (GET/PUT/POST/DELETE/HEAD) is

  attached to each request object on ingress.  The HTTP-verb-related
  interfaces are defined in ``repoze.bfg.interfaces`` and are
  ``IGETRequest``, ``IPOSTRequest``, ``IPUTRequest``,
  ``IDELETERequest`` and ``IHEADRequest``.  These interfaces can be
  specified as the ``request_type`` attribute of a bfg view
  declaration.  A view naming a specific HTTP-verb-matching interface
  will be found only if the view is defined with a request_type that
  matches the HTTP verb in the incoming request.  The more general
  ``IRequest`` interface can be used as the request_type to catch all
  requests (and this is indeed the default).  All requests implement
  ``IRequest``. The HTTP-verb-matching idea was pioneered by
  `repoze.bfg.restrequest
  <http://pypi.python.org/pypi/repoze.bfg.restrequest/1.0.1>`_ . That
  package is no longer required, but still functions fine.
