irule forward proxy w/ dns resolution
Greetings,
Currently we use our f5 for a outbound proxy to the internet. This works as I have a internal vip listening on a ip and port. traffic comes in and gets load balanced to a pool with external ips; however, we have ran into somewhat of a snag. Some of our external connections use a gtm solution that makes one datacenter active at a time. (active standby) What I would like to do is either have an irule that resolves dns on every request and updates the pool with the ip it resolves and removes the one not being used OR use an irule that resolves the dns name and points traffic to that ip. I'm currently running v9.4.8
I'm not exactly an expert on irules so any help would be appreciated. Thanks in advance.

also, since the request comes in on a rfc 1918 space. I.E the app sends the request to the vip which is a 1918 ip. I'd want to be able to specify the domain inside the irule. As in its a static variable. In a perfect world this extracting the fqdn from the uri would probably be the way to go long term, but I'm not in a position to have the app redone to at this point. I'm okay with having multiple irules.
