I have a browser app using signalR to connect with a browser base, kiosk, web app. Generally, it's ok, but over a long period of time we've found it's just un-reliable. The backend is not an asp.net net, it's self hosted signalR (along with the rest of the app)

Our population of units include Win7/64 and Win7/32. It's my understanding that web sockets are not available in Win7, so server sen events/long polling are used. So any alternative would have to have this support.

What are alternatives to SignalR that would work?
