ACL string //ACL match rules, reserved
// If SessionAffinity is set and without CookieStickySession, requests are routed to
// a backend based on client ip. If both SessionAffinity and CookieStickSession are
// set, a SERVERID cookie is inserted by the loadbalancer and used to route subsequent
// requests. If neither is set, requests are routed based on the algorithm.
// CookieStickySession use a cookie to enable sticky sessions.
// The name of the cookie is SERVERID
// This only can be used in http services
CookieSession bool
