ASP.NET MVC Route IDs with a period

Question

If I have a route with the following:

{controller}/{action}/{id}

I look at the following URL:

c1/a1/abc.

It doesn't work. This only happens when the period is at the end of the URL. Any way to get ASP.NET MVC to recognize that as part of the ID?

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

<system.web>
    ...
    <httpRuntime relaxedUrlToFileSystemMapping="true" />
    ...
</system.web>

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

This was the only method I found to work on MVC4 – user1534664 Aug 31 '13 at 11:36
Thank you. I tried 5 different answers that I found on SO. This was the only technique I found that worked. – David Burela Oct 23 '13 at 13:59

Reading through the answers to the two similar problems below, I only can suggest that you encode the period before passing it to you MVC application. It looks as the period is also treated as a delimter to a rule succh as "/".
