+## Start the SignalR circuit at a different URL
+
+Prevent automatically starting the app by adding `autostart="false"` to the Blazor `<script>` tag ([location of the Blazor start script](xref:blazor/project-structure#location-of-the-blazor-script)). Establish the circuit URL manually using `Blazor.start`. The following example uses the path `/signalr`:

+```diff
+- <script src="_framework/blazor.web.js"></script>
++ <script src="_framework/blazor.web.js" autostart="false"></script>
++ <script>
++   Blazor.start({
++     circuit: {
++       configureSignalR: builder => builder.withUrl("/signalr")
++     },
++   });
++ </script>

+
+Add the following <xref:Microsoft.AspNetCore.Builder.ComponentEndpointRouteBuilderExtensions.MapBlazorHub%2A> call with the `/signalr` path to the middleware processing pipeline in the server app's `Program` file:
+
+```csharp
+app.MapBlazorHub("/signalr");
