+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)). Manually establish the circuit URL using `Blazor.start`. The following examples use the path `/signalr`.
