/**
 * Map of HttpSession Ids to FlexSessions. We need this when registered as a listener
 * in web.xml in order to trigger the destruction of a FlexSession when its associated HttpSession
 * is invalidated/destroyed. The Servlet spec prior to version 2.4 defined the session destruction event
 * to be dispatched after attributes are unbound from the session so when we receive notification that
 * an HttpSession is destroyed there's no way to get to the associated FlexSession attribute because it
 * has already been unbound... Additionally, we need it to handle attribute removal events that happen
 * during HttpSession destruction because the FlexSession can be unbound from the session before the
 * other attributes we receive notification for.
 *
 * Because of this, it's simplest to just maintain this lookup table and use it for all HttpSession
 * related event handling.
 *
 * The table is maintained on the servlet context instead of statically in order to prevent collisions
 * across web-apps.
