Period in the MVC application URL results in Error 404

We've just had a case where a parameter to an MVC method was resulting in 404 Error because it contained a period (.) in the name. The application was running in IIS 6, .Net Framework 4, MVC 4. 

The solution was to create a wildcard application map for aspnet_isapi.dll that does not verify that the file exists, as described in the following link.
