Specifying routeTemplate with a URL fragment containing '.' char doesn't work

Question

I need to map an HttpRoute (in Asp.Net Web API) where the incoming URL has '.' character.

        config.Routes.MapHttpRoute
            (
            name: "ReturnPushPackageRule",
            routeTemplate: "v1/pushPackages/web.com.example.test",
            defaults: new
                {
                    controller = "Values",
                    action = "ReturnWebsitePackage"
                }
            );

I have the definition for the action like the following:

public class ValuesController : ApiController
{

    [HttpPost]
    [HttpGet]
    public HttpResponseMessage ReturnWebsitePackage()
    {
    .....
}
}

but I get a Method not found exception when I hit the URL. I suspect it is because of the URL having '.' char. Has anyone else comes across this and knows how to resolve?

Thanks!
