Class SessionInitializerFilter

All Implemented Interfaces:

public class SessionInitializerFilter extends Object implements Filter
A Filter that initializes the HttpSession for the HttpServletRequest by calling its getSession() method.

This is required for some operations with WebSocket requests, where it is too late to initialize the HttpSession object, and the current Java WebSocket specification does not provide a way to do so.
