internet traffic egress load balancing for https


Hi! Experts


We want to do internet traffic egress load balancing for https, depends on different URLs. because https traffic in encrypted, we plan to use irules read SNI field in https header and select a egress link. Is this method doable? or do you have any experience on this and could shed some light?


Thanks for your great help.

F5 has an entire product for this sort of SSL examination and routing - SSL Orchestrator


Trying to do this in an irule is complex and difficult, because you need to delay the server-side binding until the ClientHello has been sent and examined, and then pass the ClientHello through.


There are some irules that examine SNI headers to make decisions - have a search.

But you may find it easier to consider a ready-made and complete product that does what you require, and more.
