/**
 * Checks for a session timeout and if one has occurred pulls the view session policy to determine whether
 * a redirect needs to happen//from   w  w  w .ja v a 2 s.  c om
 *
 * <p>
 * To determine whether a session timeout has occurred, the filter looks for the existence of a request parameter
 * named {@link org.kuali.rice.krad.uif.UifParameters#SESSION_ID}. If found it then compares that id to the id
 * on the current session. If they are different, or a session does not currently exist a timeout is assumed.
 *
 * In addition, if a request was made for a form key and the view has session storage enabled, a check is made
 * to verify the form manager contains a session form. If not this is treated like a session timeout
 * </p>
 *
 * <p>
 * If a timeout has occurred an attempt is made to resolve a view from the request (based on the view id or
 * type parameters), then the associated {@link ViewSessionPolicy} is pulled which indicates how the timeout should
 * be handled. This either results in doing a redirect or nothing
 * </p>
