Abstract
A method of managing servers in a server cluster is disclosed. The health of servers is detected through passive return traffic monitoring. Server failure can be detected through TCP information or HTTP return codes. Various settings affecting number of failure thresholds and the time period to detect failures can be configured. Servers can be mapped to URLs such that passive health monitoring can be performed for URLs instead of server clusters.
