Crossroads is a load balance and failover utility for TCP-based services. It is a daemon program running in userspace and features extensive configurability, polling of backends using "wakeup calls", highly configurable dispatch modes of client requests to back ends, detailed status reporting, "hooks" for special actions when backend calls fail, support for "sticky" HTTP sessions, and more. It is service-independent; it is usable for HTTP(S), SSH, SMTP, DNS, MySQL, etc.  [edit]  Less
