Hi everyone
Hi Laurie

This should all be doable

It it possible to provide a list (2 is enough, more would be better) of
backup servers, which behave in the following way
* All requests go to the main server
* This is done by specifying all additional servers as "backup" when configuring them in the backend

* If the server goes down, all requests go to the backup
  * this is handled by setting the option above.

* if the main server goes up - requests continue going to the backup
(until manual intervention)
* This is done by specifying a cookie on your backup server - the requests will then continue to be handled by that server until the session expires (or the server goes down)

/optionally/
* if the backup server goes down, all requests go to backup 2
* If you have multiple backup servers make sure you do not specify "option allbackups" as this will send traffic to all of your backup servers, rather than progressing through them.
