MVC 4 routing - ignore requests for images

问题

I'm trying to prevent users from making requests to access images on their own in my web application, so the user shouldn't be allowed to make this type of request:

sitename/Images/test.jpg

I've tried specifying a route to ignore in RouteConfig.cs but it still serves images on their own, is there a way to prevent this?

This is what I've tried:

routes.IgnoreRoute("{file}.jpg");
routes.IgnoreRoute("Images/{file}.jpg");
routes.IgnoreRoute("{resource}.jpg");
routes.IgnoreRoute("Images/{resource}.jpg");

回答1:

If you want to ignore folder you can write like this:

routes.IgnoreRoute("Images/{*pathInfo}");

if you want to ignore only certain files in folder you can use this overload of IgnoreRoute() like this:

routes.IgnoreRoute("{Images}", new { assets = @".*\.(jpeg|gif|jpg)(/.)?" });

As you can see constraints parameter can be implemented like RegExp.
