Is your feature request related to a problem? Please describe.

I am trying to better understand how the Azure SignalR service works together with Blazor Server running on top of Azure App Service sitting behind Azure Front Door.

I'd like to see a detailed diagram showing the communication flow from the starting point of a user opening the web page, ideally with Azure AD based auth steps as well, while making it clear which components initiates the connections to where.

I know that Azure Front door doesn't support WebSockets this is why Azure SignalR service must be used, which means SignalR can never just connect to the App Service behind front door, right? You see this is really not clear to me :)

Additional context

Thank you!!
