      public void destroy()
      This method destroys the filter.

      Called by the web container to indicate to a filter that it is being taken out of service.

      This method is only called once all threads within the filter's doFilter method have exited or after a timeout period has passed.

      After the web container calls this method, it will not call the doFilter method again on this instance of the filter.
