>From the Cisco documentation: Cisco ACE provides stickiness that allows the same client to maintain multiple simultaneous or subsequent TCP or IP connections with the same real server for the duration of a session. Cisco ACE supports the following sticky methods: . Source or destination IP address . Cookie . HTTP header, and Generic Protocol Parsing for session level persistence such as SSL session ID

So unless each client sends a unique identifier in the http payload, I don't think you'll be able to do it. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
