Question

I have some very basic SignalR code running on the js client:

var conn = $.connection("@Url.Content("/echo")");

conn.Debug = function (msg) {
    console.log(msg);
};

conn.start();

This code executes and works, except I get a 404 Error. The JS is trying to access http://localhost:32344/echo/negotiate and it can’t find it. If I hit the url without the “negotiate”, the request completes.

I did not touch the Global.asax, and the server code is as basic as it gets, but there are not calls to this code from the client yet:

public class SpatialHub : Hub
{
    public void Send(string data)
    {
        Caller.Debug("sent!");
    }
}

Any thoughts would be appreciated. Thanks!

You’re mixing the “High level hub” client side server code with the “low level connection” client side API.
