In principle a proxy is just a server like any with the big difference that there is no unique data except for the config file which needs to be shared among the members of the cluster, so it's about the simplest service you can find to cluster.. Possible methods: - Layer 7 load balancers - Normal clustering using virtual IP addresses and software within the cluster monitoring the state of other nodes and taking over IP addresses when needed, and having clients distributed among these addresses using external configuration (proxy.pac, manual config etc..) - Client-side load balancing using proxy.pac scripts. - round-robin DNS based load balancing and probably a few additional methods as well.. If you use authentication then there is a few additional things to consider: - Basic authentication is per proxy name, so proxy.pac based load balancing may be a bit annoying unless the users is kept on the same proxy during his whole session - NTLM/Kerberos and to some extent digest authentication is a bit picky about the server identity so layer 7 load balancing may not be the best there (easily confuses clients unless the setup is carefully done).
