NimbostratusUse a table instead of a cron job
I have source address persistence configured on a virtual server with a 15 minute timeout for a few caching servers. I'm using a cron job, "b persist pool www.abc.com delete", to force a new load balancing decision every 15 minutes to ensure traffic is distributed to all servers in case a server goes down temporarily. Is there a way to use the table commands to perform this same action? It looks like there should be, I'm just having a problem understanding how to delete the connections every 15 minutes using the table commands.

i never tried session/table command to delete persistence record. anyway, i think you may create a new virtual server with session/table command irule, create a pool with virtual server as a member and then assign health monitor with 15 minutes interval to the pool. so, health monitor packet will trigger the session/table command irule.
by the way, since you are load balancing cache servers, don't you want to use carp instead of source address persistence?
