Jsessionid between Data Centers

Hi santsboy - yes there is, but not using JSESSIONID. The F5 persistence cookies themselves provide this. What you need to do is;

• establish connectivity from LTMs in site A ==> servers in site B
• establish connectivity from LTMs in site B ==> servers in site A
• create pool in site A which includes servers from site A and servers from site B (at a lower priority group than the site A servers)
• create pool in site B which includes servers from site B and servers from site A (at a lower priority group than the site A servers)
• enable cookie insert persistence at each site (I assume you have already done this)

This means that if you hit site A (for example) with no persistence cookie, only servers in site A will be chosen, however if a user session moves between sites (and it does happen, even when GTM persistence is enabled), the LTM looks at the cookie (which decodes to an IP:port after all) from the server in the other site and when it sees that server in it's pool, it sends the request to that server, even though that server may not be currently 'activated'.

I hope that makes sense - let me know if any questions.
