Abstract
Switch-implemented methods of maintaining persistence of a session between a client node and a server node are described. A response from the server node to a first request from the client node is received. The first request includes a uniform resource identifier (URI). The response includes a cookie that includes a random session identifier. The response also includes rewritten uniform resource locators (URLs) that include the URI and the session identifier. The session identifier from the cookie and the identity of the server node are stored. A second request is received from the client node. The second request includes a rewritten URI (when the client node does not support or enable the use of cookies). The session identifier from the rewritten URI is matched to the session identifier in memory to identify the associated server node. The second request can then be directed to the server node.
