CirrusHow does F5 process a traffic
Hi experts,
Wanted to ask as I keep having hardtime googling to find an answer.
How does F5 process a traffic when a client initiates?
Does assume 3 way is completed, will F5 process SSL before irule? or F5 will check the irule first?
TIA
Take a look at this video from : https://youtu.be/qCLEw5xIZ7s
It is for BIG-IP 12.1, but it is still relevant and very helpful.
I watched it for like 45 minutes in Slow-Mo and replicated his drawing into a Visio. I attached my Visio as png.
iRules are executed before, while and after the SSL handshake. Depending on the Event you choose.
when CLIENT_ACCEPTED { ## happens when the TCP three-way handshake is completed successfully, before the SSL Handshake when CLIENTSSL_CLIENTHELLO { ## happens while the SSL Handshake when HTTP_REQUEST { ## happens after the SSL Handshake

f5mkuDefaultthis is my same understanding, really depends on the event type used. Will check that video and visio file. Thanks Daniel.
