c# - Multiple signalR connections/hubs on your website

Question

If I have multiple pages that could use multiple hub classes, what is the best way to manage this?

For instance:

• Is it bad to navigate to another page in the website and essentially "reopen" the connection to the same hub class that was open on the previous page?

• Am I correct in thinking that opening multiple hub connections on a page is ok because they are all unified in one connection, even if they are different hub classes?

Answer 1

You can have multiple hubs sharing one connection on your site. SignalR 2.0 was updated to handle multiple hubs over one signlar connection with no lost in performance.

Official docs: http://www.asp.net/signalr/overview/signalr-20/hubs-api/hubs-api-guide-server#multiplehubs

All clients will use the same URL to establish a SignalR connection with your service ("/signalr" or your custom URL if you specified one), and that connection is used for all Hubs defined by the service.

There is no performance difference for multiple Hubs compared to defining all Hub functionality in a single class.
