“The resource cannot be found.” error when there is a “dot” at the end of the url

If you are using .NET 4.0, you can set this flag in the system.web section of your web.config and it will be allowed:

<httpRuntime relaxedUrlToFileSystemMapping="true" />

I’ve tested it and it works. Haack has an explanation of it.
