WACheckSessionExpiration

public class CheckSessionExpiration
extends InsertableServletImpl

This Servlet checks the session for expiration and if the session is expired it redirects to expirationURL. This also handles server failover conditions by checking against the parameter sessionRestored in DynamoHttpServletRequest. If the user is accessing dynamo site and the dynamo that is serving the user goes down, and if another server handles the subsequest request from user, the session of the user will be invalid and the new dynamo server creates a new session and restores session information of the user in new session from session backup server. sessionRestored is set to now invalid old session id.
