Handing MVC paths with dots in the path

Lot of developers don't know how to handle a situation with a dot (.) in the path for an MVC project. The path looked something like this:

http://domain.com/aspnet/CLR4.0

The MVC routes didn't work for this path and the standard IIS 404 handler served up the page instead. However, the following URL did work:

http://domain.com/aspnet/CLR4.0/

The only difference is the trailing slash. For anyone that runs into the same situation, the below link shows the reason and the solution.
