signalr

I'm using long polling with SignalR. I've found that user session ends (ASP.NET Session_End is being called) right after singalr based webpage makes /signar/ping request ( as shown in this screenshot ). I went through http://www.asp.net/signalr/overview/signalr-20/hubs-api/handling-connection-lifetime-events but couldn't figure out clear answers following questions. How to keep ASP.net user session alive from a signalr client webpage? What is the actual purpose of /ping? Is the timing for this /ping call configurable? The entire purpose of the /signalr/ping request is to keep ASP.NET sessions

I'm using ASP.NET MVC 4 and SignalR 2.1.1. My website works great for most users in all browsers, but there is an error that only occurs for certain user on specific isp-networks. The error is this: The connection to ws://domain.com/signalr/connect?transport=webSockets&clientProtocol=1.4&connectionToken=78ZpJ007jmlLSBbVzDVbfpYahHsveD3x8%2Bc5PC9h%2FgeOz5zNgE8SaKWaQAasGNLe%2BvJeI6ux6IqW0E8WQWqP6Ps%2FXjc8WPbG7G47oHSxRSx7nVj0leVa1DdXzEXnLQ%2BA&connectionData=%5B%7B%22name%22%3A%22homehub%22%7D%5D&tid=4 was interrupted while the page was loading. For the same users receiving this error, logging in

I can get this tutorial to work in a new project, but not in my existing project. My project is an ASP.Net MVC 4 web application with the following attribute in the web.config file: <appSettings> <add key="webpages:Enabled" value="true"/> </appSettings> This is because my application is a Single-Page-Application, which uses AngularJS on the client side. The only page in my application is index.cshtml, to which I've added the relevant code for signalR: <!-- signalR chat --> <script src="~/Scripts/jquery.signalR-1.0.0.js"></script> <!--Reference the autogenerated SignalR hub script. --> <script

I am using SignalR in my ASP.NET web application. Here I am calling client from outside to hub class using IHubContext . I need to get the current user's connection ID in order to send messages to the current user only. How can I get the connection ID on the client side? Ruchira Yep. You can use $.connection.hub.id . There's another way also, you can get connection id into your controller from hub by invoking a method of hub and you can return the required ID from there. Controller Code var HubContext = GlobalHost.ConnectionManager.GetHubContext<"ChatHub">(); //`ChatHub` can be your Hub Name

When the user logs in on my site, they select from a dropdown which group they belong to. On the login postback, as they are logged in, I'd like to assign them to the correct SignalR group. As per the documentation here , I can join it client-side via: contosoChatHubProxy.server.joinGroup(groupName); Is there a way to assign the group from the controller? I can call the Hub like: var hub = new NotificationHub() hub.JoinGroup(selectedGroup); but the Context in the hub method is null. Is this possible, or am I approaching this problem incorrectly? Thankyou for any advice. You shouldn't new up a

I have a Windows Service that I'd like to periodically publish some data. I know I can use the .NET HubConnection object to create a proxy to a SignalR hub and send a message through it but since the web app is hosted on an IIS web farm that can get a bit hacky. The web farm hubs are connected using the SQL Server-based SqlScaleoutConfiguration backplane. What I'd really like to do some thing like this: var config = new SqlScaleoutConfiguration(sqlConnString); GlobalHost.DependencyResolver.UseSqlServer(sqlConnString); //Redundent?? var messageBus = new SqlMessageBus(GlobalHost
