signalR generating different ID for various instan

问题:

I have created web chat application using signalR. When user is logged in, user can open only 3-4 tabs and each time different connection ID is generated. I want that when we open new tab or refresh the page new connection id should not be generated. I want to use the existing connection id. For that I tried to implement the LocalStorage variable to store the hub connection. But Problem is i am unable to parse the value of localstorage variable.

Can Anyone give me the solution to my problem or can anyone give me any other solution to the problem?

I have already tried this http://kevgriffin.com/maintaining-signalr-connectionids-across-page-instances/ but it dosen't work for me

回答1:

If user is authenticated you can store different connectionIds in the HashSet. The key for the HashSet will be the user's name.

You can use this method even if you are not authenticated. In this case you can use SessionId instead of username.

EDITED:

I have found another method. In this article Alex Ford advices to limit your connections to 3.
