Different persistence each pool under a single virtual server

I think you need to choose a valid event for the [SSL::sessionid] command. http://devcentral.f5.com/wiki/default.aspx/iRules/SSL__sessionid.html

 

 

I also recall that you need to assign a persistence profile to the VIP in order to use certain persist commands in an iRule (like ssl). That would mean you need to do "persist none" for pool C. http://devcentral.f5.com/Default.aspx?tabid=53&view=topic&forumid=5&postid=1276
