    Decorator to make a view only accept particular request methods.  Usage::

        @require_http_methods(["GET", "POST"])
        def my_view(request):
            # I can assume now that only GET or POST requests make it this far
            # ...

    Note that request methods should be in uppercase.

    Decorator to support conditional retrieval (or change) for a view
    function.

    The parameters are callables to compute the ETag and last modified time for
    the requested resource, respectively. The callables are passed the same
    parameters as the view itself. The ETag function should return a string (or
    None if the resource doesn't exist), while the last_modified function
    should return a datetime object (or None if the resource doesn't exist).

    If both parameters are provided, all the preconditions must be met before
    the view is processed.

    This decorator will either pass control to the wrapped view function or
    return an HTTP 304 response (unmodified) or 412 response (preconditions
    failed), depending upon the request method.

    Any behavior marked as "undefined" in the HTTP spec (e.g. If-none-match
    plus If-modified-since headers) will result in the view function being
    called.
