ASP.NET MVC Route IDs with a period [duplicate]

Question

This question already has an answer here:

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?

Answer 1

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 "/".

Answer 2

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.
