How can an iRule detect an Edge client?

Hi all,

 

 

I'm trying to create an iRule that will detect when an Edge client has connected. There doesn't appear to be a user-agent sent, at least I can't see any HTTP_REQUEST event firing when the client connects. This is for a set of LTMs that are load balancing a number of APMs and need to send Edge clients to specific APM appliances.

 

 

Cheers.
