Abstract
A method and apparatus for establishing session persistence between a client and an origin server are provided. The session persistence can be managed by an intermediate cache server. The persistence is established by inserting an identifier and origin server address in a cookie or URL. Alternatively, the persistence is established by a table mapping a source IP address or a session ID to a specific origin server. Subsequent requests from the same client are mapped to the same origin server using these methods of establishing persistence.
