Hello,
My goal is to have two separate web farms in different geographical locations for performance and redundancy.
With two separate farms (both with different public IP addresses and different ISPs), how do I setup DNS (or anything else required) to point to both locations and pick the closest (or fastest) one?
Is it as simple as putting both IP addresses as A records in the DNS for the domain?
ALSO, I am using forms authentication for the applications. How do I ensure that if someone is logged in at one farm, it carries over to the other if they wind up there when browsing through the site?
Thanks,
John Chapman
