title: SignalR, Limited unique connections (opened tabs) IIS8, Windows8
body: <p>It is impossible to use SignalR, when several tabs opened  with unique ids assigned to each tab (see. <a href="https://stackoverflow.com/questions/10426163/when-signalr-made-8-10-connections-at-a-time-live-chat-doesnt-work">When SignalR made 8-10 connections at a time live chat doesn&#39;t work</a>).</p>
  
  <p>But. there is a workaround I described in this stackoverflow issue. The idea is to overwrite connectionid  in order, that every opened tab would have the same connection id:  thus, logicaly, in my particular case, there is no reason to have unique ids for each tab, 'cos each tab is opened by one MyApplicationUserId.</p>
  
  <p>Anyway, it has been noticed in stackoverflow (see <a href="https://stackoverflow.com/questions/11522090/signalr-how-is-a-duplicate-connection-id-handled">SignalR How is a duplicate Connection Id handled?</a> ), that connectionid must be unique. And they say, that IConnectionIdGenerator  will be removed in an upcomming release.</p>
  
  <p>So, this is a kind of blind alley. I must use unique ids, but I cannot use SignalR with several browser tabs opened.</p>
  
  <p>Thank you.
