Thanks for your help. The [HTTP::host] and pool names were coming out correctly. It seems that it didn't like that I was pointing to some pools that were created via iapp. It was logging
TCL error: /Common/OneRule - no such pool: serverGroupA_pool (line 1) invoked from within "pool $usepool"
When I created pools manually, it worked just fine.
Hi J,
We were doing a 1:1 NAT from the public to the virtual IP, so practically every node gets mapped to it's own public IP. You might imagine how over time we have amassed quite a large amount of public addresses, with more servers going up all the time. Being able to use several pools under one VIP makes things a lot easier for me. I don't need to beg for more addresses every few months, and I don't need to worry about public DNS if I need to move a URL to a new server. I would just need to update the pool it uses in the data group and it would instantly take effect.
