We have seen the behavior with > both a Cisco and a F5 load balancer. Probably persistent connections making the load balancer screw up. My guess is that the load balancer only looks at the first request on a connection and then assumes every following request will be from the same user. When using a proxy the only guarantee there is that the request is from the same proxy... connections in HTTP is hop-by-hop, not end-to-end, and the same connection from a proxy will be reused for requests from different users of that proxy. Try "server_persistent_connections off" in squid.conf, or disabling persistent connections / keep-alive on the web server. Regards Henrik
