Let ie6 also support websocket using flash packaging_javascript skills

Even ie9 does not support websocket, let alone ie6, but websocket can develop such cool functions, how can we let ie stop us?
But what should we do?
Use flash packaging

The specific flash code is as follows :

Copy the code The code is as follows:

package {
