405 Error (Method Not Allowed) when using DELETE method to POST to controller

[D.W. Small]

I am using TG 2.1 and am receiving an error when I attempt to send the DELETE method to the controller.

GET and POST method both work fine, but for some reason the DELETE method gives a not allowed error (405)

class DELETEController(RestController):

    @expose('json')

    def product(self, product_guid):

         pass

Is there a simple way to allow/expose the delete method in this controller ?
