How to register a route that admits a dot in the path?

Question

I want to implement a routing system that admits a dot in the url. Currently I handle urls like:

mydomain/User/Details/raguilar

but if the username has a dot, then it is generated as:

mydomain/User/Details?username=r.aguilar

I tried to add the following route:

routes.MapRoute(
            name: "Users",
            url: "User/{action}/{username}",
            defaults: new { controller = "User", username = UrlParameter.Optional },
            constraints: new { username = @"\w+\.?\w+" }
        );

and all seems to be ok, but when I clicked on the url I received an error that says that the related resource is not found or something like that.

Is there some way to fix this issue?

Answer 1

In order to solve this problem I should add the following line to the system.webServer/handlers element:

<add  name="ApiURIs-ISAPI-Integrated-4.0" 
      path="/user/*" 
      verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" 
      type="System.Web.Handlers.TransferRequestHandler" 
      preCondition="integratedMode,runtimeVersionv4.0" />

Where user is the controller to which belong the paths that will contain the dot.
