from django.utils.decorators import decorator_from_middleware

from django.middleware.http import ConditionalGetMiddleware

from django.http import HttpResponseForbidden

from django.http import HttpResponseNotAllowed

conditional_page = decorator_from_middleware(ConditionalGetMiddleware)

        def inner(request, *args, **kwargs):

            method = request.META.get("REQUEST_METHOD", None)

            if method not in request_method_list:

                raise HttpResponseForbidden("REQUEST_METHOD '%s' not allowed" % method)

                return HttpResponseNotAllowed(request_method_list)

            return func(request, *args, **kwargs)

        return inner

    return decorator
