How to select a pool based on client's hostname?

Actually, per BZ360270, the -ptr result isn't cached like other resolution responses, so it makes sense to manually cache the result in the session table. I'm working on a revised iRule now.

 

 

Also note that you'll need to install HF1 or higher for 10.2.1 for the -ptr resolution to work:
