ASP.Net MVC - Why is a controller being created for favicon.ico?

Question

I am using a custom ControllerFactory (to use Castle Windsor's IOC to create controllers), and I notice it's getting requests to create a controller for "favicon.ico". I have put a favicon.ico file in my Content folder, but I'm still getting these requests.

How do I resolve this and serve static content without trying to create controllers?

This was happening to me because browsers try to look for the favicon.ico in your root and for some reason asp.net thinks it's a controller, and it filled my logs with the error "favicon.ico controller not found", I don't know if this is what you are talking about. – Beamer

Add the following route:

routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });

Why not just routes.IgnoreRoute("favicon.ico")? – Wench

The suggested IgnoreRoute ignores favicon.ico in any folder, not just the root. I think it comes from Phil Haack's blog (haacked.com/archive/2008/07/14/…) – Biffin

Oh, and it should be \. for the . in the regular expression i.e. favicon\.ico – Biffin
