what is the main difference between persistence and one connect.

peristence is meant to send the client traffic to the same backend server (necessary if the application builds sessions and those are not shared among the backend servers)

one connect is meant to optimize connections usage between the BIGIP and the backend servers. That mean, reduce the TCP connections open/close cycle. That will accelerate connections client<>backend and reduce resource usage on backends.

Vijay, here are a couple of links to get you familiar with the idea (from an F5 pespective)

thanks, what will happen if we use oneconnect and persistence in https VIP.

what will happen if we use oneconnect and persistence in https VIP.

with clientssl and http profiles, oneconnect does per request load balancing and also reuse server-side (between bigip and server) connection. that means each http request in one tcp connection can be load balanced to different pool member.

persistence makes bigip to send request to pool member which client was load balanced to.
