Serving favicon.ico in ASP.NET MVC

What is the final/best recommendation for how to serve favicon.ico in ASP.NET MVC?

I am currently doing the following:

• Adding an entry to the very beginning of my RegisterRoutes method:

  routes.IgnoreRoute("favicon.ico");
  

• Placing favicon.ico in the root of my application (which is also going to be the root of my domain).

I have two questions:

• Is there no way to put the favicon.ico somewhere other than the root of my application. It’s pretty icky being right there at the same level as Content and Controllers.

• Is this IgnoreRoute("favicon.ico") statement sufficient – or should I also do the following as discussed in a blog post from Phil Haack. I’m not aware of ever having seen a request to favicon.ico in any directory other than the root – which would make this unnecessary (but it’s good to know how to do it).

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