disconnect client from server side signalr

Question

I'm using SignalR 1 with MVC4 C# web application with form authentication. I have a code in my layout page in JavaScript :

$(documnet).ready(function(){
       connect to hub code ...
})

I want to disconnect a user form the hub and start connect again after he does a login and validate ok. I want to do it from server side inside my account controller and method :

public ActionResult LogOn(LoginModel model, string returnUrl)
{
    if (ModelState.IsValid)
    {
        if (System.Web.Security.Membership.ValidateUser(model.UserName, model.Password))
        {
            FormsAuthentication.SetAuthCookie(model.UserName, false);
            ....here , disconnect from hub
            ....to make the user reconnect     
}

The reason I want to do it is because SignalR throws an error if user changed to authenticated after login and the connection remains . The error is:

The connection id is in the incorrect format.

Answer 1

You cannot stop and start SignalR connections from the server. You will need to call

$.connection.hub.stop(); //on the client before the user attempts to log on and then call 
$.connection.hub.start(); //after the log on attempt has completed.
