Hi, All: Let's say I have 2 or more different webhosts that host the web pages for a particular domain. The web pages are different on each host for testing purposes. Each of the webhosts of course has different DNS. Is there a DNS rotation service out there that will reliably rotate visitors through the different webhosts (Scenario A)? Or rotate by time-slicing (Scenario B) e.g. (Scenario A) Visitor 1 goes to webhost#1, next visitor to webhost#2 and so on, in round robin fashion, and rotating back to webhost#1. (Scenario B, this is more sophisticated) In addition to Scenario A, there is a timer. Let's say the time is set for 5 minutes. Let's say visitor v happens to be assigned to webhost w. Once his stay at webhost w exceeds the time limit of 5 minutes, he is automatically assigned to the next webhost in the round robin, i.e. w+1, in the round robin order. So, if he tries to refresh a page or click a link on webhost w, at a time that is beyond 5 minutes, he is directed to the next webhost in the round robbin, i.e. webhost w+1. Any advice will be appreciated. Thanks will be given.
