What do you mean by "cannot get them to work"?

Do you get an error?

Are you using IIS 7 or 8?

Hi Morten,

We follow the steps in readme file.

The RouteTable.Routes.MapHubs() is deprecated so we added a OwinStartup class, following this article:

http://www.asp.net/signalr/overview/signalr-20/getting-started-with-signalr-20/upgrading-signalr-1x-projects-to-20

We can compile the VS solution successfully, but in Dynamicweb we can only start if we add the appSettiing <add key="owin:AutomaticAppStartup" value="false" />.

I've attached the VS solution.

Hello.

I think the problem is that it cannot find the signalr/hubs file that is managed by the framework. Let me tell you what I have done, and maybe you will be able to spot what went wrong.

- Created an empty web application in VS. Followed the steps to create a chat app (created a Startup class and a Hub class) as per one of the tutorials on the web. Changed the references for the scripts to correct the scripts references in the page I created to test the chat. Chat functionality works.

- Placed the DW application contents in the web site created in the previous step. After changing a few bits the web.config and removing the Startup class (conflicts with a DW class, which I presume is the equivalent startup class DW uses for its SignalR purposes), both the Admin site and the front end for DW work. My example page loads, but there is an 404 error for http://signalrchat.local.dynamicweb.pt/signalr/hubs.

The test page is at the root of the web site, and the references in the file are as follows:

    <script src="/Scripts/jquery-2.1.1.min.js"></script>

    <script src="/Scripts/jquery.signalR-2.1.2.js"></script>

    <script src="signalr/hubs"></script>

What I am wondering is that the signalr/hubs is placed somewhere else because of DW configurations. Can you think of anything that I could try to get it working?

Hello.

Just noticed another thing: a simple test app that I have for this works when I Run in IIS Express, but not on the local IIS.

Tried to see if the same thing happens on the DW project but cannot. It start the DW configuration process and gets stuck. IIS version on local machine is 7.5, by the way.

Hi there,

Could it be that Dynamicweb is intercepting the request and returns a 404? Try to add the following code to your Global.asax:

 public void Application_OnPreRequestHandlerExecute(object sender, EventArgs e)
    {
      if (!HttpContext.Current.Request.Url.ToLower().Contains("signalr"))
      {
        GlobalAsaxHandler.Application_OnPreRequestHandlerExecute(sender, e);
      }
    }

(Code typed in this editor so it may not completely work)

This should bypass requests for all signalr URLs...
