ColdFusion leverages the browser-supported HTML5 native WebSocket to provide server controlled client-to-client communication. If a browser currently does not have HTML5 support or the native WebSocket support, ColdFusion uses Flash player as the fallback option. Fallback to Flash is smooth and automatic.See also, Browser support for WebSocket.The following table provides the fallback plan for ColdFusion WebSocket:


What happens

Native WebSocket support available

Establishes a WebSocket connection.

Native WebSocket unavailable, but Flash is installed

Automatically falls back to Flash.

No native WebSocket support or Flash installation

Sends a message indicating that the connection is not successful.To proceed, either move on to a compliant browser or install Flash.
