public class SessionInitializerFilter extends Object implements Filter
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.
