+Map the SignalR hub of a server-side Blazor app by passing the path to <xref:Microsoft.AspNetCore.Builder.ComponentEndpointRouteBuilderExtensions.MapBlazorHub%2A> in the `Program` file. The default Blazor hub path is `/_blazor`, and the following example sets the base path of the default hub to `base/path`:
 
 ```csharp
-app.MapBlazorHub("base/path");
+app.MapBlazorHub("base/path/_blazor");
 ```
 
 The benefit of using <xref:Microsoft.AspNetCore.Builder.ComponentEndpointRouteBuilderExtensions.MapBlazorHub%2A> is that you can map patterns, such as `"{tenant}"` and not just concrete paths.
 
 You can also map the SignalR hub when the app is in a virtual folder with a [branched middleware pipeline](xref:fundamentals/middleware/index#branch-the-middleware-pipeline). In the following example, requests to `/base/path/` are handled by Blazor's SignalR hub:
 
 ```csharp
-app.Map("/base/path/", subapp => {
-    subapp.UsePathBase("/base/path/");
+app.Map("/base/path", subapp => {
+    subapp.UsePathBase("/base/path");
     subapp.UseRouting();
-    subapp.UseEndpoints(endpoints => endpoints.MapBlazorHub());
+	  subapp.UseAntiforgery();
+    subapp.UseEndpoints(endpoints => {
+        endpoints.MapBlazorHub("/base/path/_blazor");
+        endpoints.MapStaticAssets();
+		    endpoints.MapRazorComponents<App>()
+				.AddInteractiveServerRenderMode();
+	});
 });
 ```
