i have two webservers and the next zone
web1.example.org IN A 10.0.0.1
web2.example.org IN A 10.0.0.2
example.org IN CNAME web1.example.org
example.org IN CNAME web2.example.org
The problem its the php session, you go to web1.example.org and later the dns responds web2.example.org.
How can i fix this?
