What is the best way create a session-less site?

This is the process i use to keep a session-less site?  Does anyone have any better suggestions? var memberObj = { MemberID = request.MemberStruct.userData.MemberID, SessionKey = request.MemberStruct.userData.SessionKey, }; cfcookie( name = “cookiename”, expires = 30, value = “#encrypt(serializeJSON(memberObj,true),application.key,”cfmx_compat”,”hex”)#”, httpOnly = true, preserveCase = true, secure = true );
