How often JSESSIONID and JSESSIONMARKID get updated
Need some help in understanding the session cookies in the SAP NW AS Java. I am using SAP NetWeaver Application Server 7.20 / AS Java 7.30
I have a web page that makes concurrent requests to the NW server using jQuery-Ajax every 30seconds.
I am seeing the JSESSIONMARKID is getting updated very often(mostly every 30secs-1 min but not consistently)and the JSESSIONID gets updated every 1-2 mins but this is particular pattern.
My doubt is does the JSESSIONID gets updated every 1 or 2 mins? My assumption was that once JSESSIONID is issued it remains same and the server keeps track when was the last user activity and based on inactivity for configured period of time the session gets timed out and if user comes back after session out with a JSESSIONID, he will be redirected to login page.
Kindly help me in understanding the JSESSIONID and JSESSIONMARKID cookie update process.
Thanks in advance for your valuable reply.
