A couple of DNS Round Robin questions please:
I am running basic MS DNS round robin which sends requests to one of 2 identical web servers.
I understand that MS DNS server will alternate requests between the multiple IPs for same DNS records.
1. When the DNS server sends a request to box 1, will box 2 ever receive a request from that same session?
In other words, do I need to worry about session variables not persisting during a client's viewing because they have been bounced from box to box?
2. How does MS DNS alternate between boxes exactly? I host about 1500 websites, whos DNS records are identical. So say the DNS server gets a request for website1.com and sends it to box 1 will a request for website2.com be sent to box2? or will the request be sent to box1 and only the next request for website1.com be sent to box2? Is there a preference of box by default?
