So I have mod_proxy setup pointing at
ProxyPass / http://www.mydomain.com/
ProxyPassReverse / http://www.mydomain.com/
and www.mydomain.com
has 4 A records (ie DNS load balancing) will mod_proxy pick 1 ip from that list for all it's worker processes and expire on the ttl of the DNS record, or will each worker process pick its own IP from that list?
I'm setting up a proxy sitting in front of a web server that is using this DNS load balancing, and I don't want to have to hard-code their IP addresses into BalancerMember directives as then they can't add & remove IP addresses without changing the proxy too.
