Hi I'm just in the process of setting up a clustered LAMP infrastructure to distribute my web traffic to a number of web servers via a reverse proxy. I'm fairly sure about the direction I'm going in with everything art from the reverse proxy. I don't want any single point of failure in the setup so ideally I'm going to need a couple of reverse proxy instances running. The only way I can think of failing one over to another is via DNS though. I'm sure that would work but there could be down time during the DNS switch, even if it is just a few minutes. Can anyone suggest a better way to handle a reverse proxy fail over so that if one reverse proxy goes down the other will take over. Thanks in advance for any advice!
