Hello Alex.

You could configure an iRule that routes traffic base on the "nodeX" value of the JSESSIONID cookie, checking first if this specific member is UP using "active_members" command.

https://clouddocs.f5.com/api/irules/active_members.html

Config details.

• Create an iRule
• create a generic pool with all members
• create specific pools with only one member (let say, node1, node2, ...)

iRules steps:

1. Get the "nodeX" value.
2. if "[active_members pool_nodeX] == 0" use generic pool
3. if "[active_members pool_nodeX] > 0" use specific pool (pool_nodeX)

Hope this helps you.

Regards,

Dario.
