Thanks for the response chris

Unfortunately the servers here are not web servers, so setting a cooke is not an option. I also need new requests to go to the backup - not just sessions already in play.

It's an instance of Redis, (a key value store). The main server would be the master, with the backup being the slave. If the master goes down and write operations get sent to the slave, we cannot send ANY requests to the master till we have been able to re-sync them (which is a manual operation)
