I assume this is simpler because it is part of a (older?) Third-party library, and it is easier to just follow the instructions that tell you to install something in web.config . You should be able to ignore requests for *.ashx , ignoring routes in *.ashx files. You should use something like this, but I have not tried it myself:
routes.IgnoreRoute("{resource}.ashx/{*pathInfo}");
