问题 I have WebApi OWIN hosted Web Server/Winforms Client application. Additionally I am using SignalR for client/server communication. When running under IIS Express while debugging Application_Start method in Global.asax.cs is executing just fine. On IIS 7.5 same code in Global.asax.cs will not execute when website is started in IIS Manager Application_Start only fires when I call it from a page http://localhost:7000/SignalR/hubs or Client sends SignalR request first time around and after that

问题 I'm using SignalR with ASP.NET 4.5 webforms. I wasn't able to make the client talk to the server and vice versa. What I want to achieve is simply being able to to test how the Client can trigger a server function and how the server can trigger a client function. Here's the code I use: Client Side Code (HitCounter.aspx) <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script type="text/javascript" src="Scripts/jquery-1.8.2.js"></script> <script src="Scripts

Not getting distributed/disparate Angular site to talk to SignalR in WebAPI

由 梦想与她 提交于 2020-01-06 02:45:07
问题 I very new to SignalR and I am trying to integrate it with an AngularJS site and WebAPI. I followed greate this example to begin with. However, as I mentioned, the website I am working on will live on a different server to the WebAPI project. In my dev environment I have set up a local site for Angular, hosted in IIS on localhost:60000/127.0.0.1:60000 and the WebAPI lives on localhost:31374 (in VS2013, using IIS Express.) This is to simulate the 2 different servers the projects will live on.

OnDisconnect and Logged on Users after recycle?

由 廉价感情. 提交于 2020-01-05 05:49:07

And so I ask : When a user connects , I generate him a token , keep it in the user cookie , and when OnConnect is called , I attach a connectionId with that token. (the same way where onDiconnect is called , I set a value in the dateDisconnected ) This will also
