この目的のために制約を使用します。例:
routes.MapPageRoute("CMS", "{*friendlyUrl}", "~/index.aspx", true, null, new RouteValueDictionary { { "incomingUrl", new CatchallConstraint() } });
CatchallContraint は、IRouteConstraint を実装する必要があるクラスです。
Match メソッドでは、ファイル拡張子を確認し、asp 拡張子の場合は false を返します。
これが私の実装(vb.net)です-web.configで構成できるため、必要以上ですが、アイデアはわかります。
パブリック クラス CatchallConstraint は System.Web.Routing.IRouteConstraint を実装します
''' <summary>
''' If AppSettings: CatchallIgnoredExtensions doesn't exist, these are the default extensions to ignore in the catch-all route

Public Const DefaultIgnoredExtensions As String = ".jpg,.gif,.png"
''' <summary>
''' For the catch-all route, checks the AppSettings: CatchallIgnoredExtensions to determine if the route should be ignored.
''' Generally this is for images - if we got to here that means the image was not found, and there's no need to follow this route
