What is the browser support for WebSocket in IE7 and how does it differ from other browsers?

WebSocket is not supported in Internet Explorer 7. To provide WebSocket support for IE7, you can use a polyfill like SockJS or Socket.IO which fallback to other technologies like long polling or Flash sockets to provide similar functionality across different browsers. 

// Example code using Socket.IO for WebSocket support in IE7
<script src="https://cdn.jsdelivr.net/socket.io/1.4.5/socket.io.min.js"></script>
<script>
  var socket = io.connect('http://yourserver.com');
  socket.on('connect', function() {
    console.log('Connected to server');
  });
</script>
