mvc: does the favicon.ico also look for a controller?
You can also specify the ignore route with constraints
routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });
The top answers are correct.
routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });But for newer versions of MVC you must add this at the top of the RegisterRoutes method in RouteConfig.cs (so somewhere before routes.MapRoute(..) is called).
