Any Help please. Thanks.

Answer 1

Windows Azure Web Sites has recently added support for the WebSocket protocol. Both .NET developers and node.js developers can now enable and use WebSockets in their applications.

There is a new option on a web site’s Configuration tab to enable WebSockets support for an application.

For students struggling with socket.io on Azure

I've struggled for 2 days with this. I was using a student free tier for the service app and apparently that was part of the problem.

I made a B1 plan app service with my student credits. After uploading my node.js app it worked out of the box.

After that, I downscaled it to a free tier and it still works now(fingers crossed). This might help for students struggling with socket io on azure.
