At least for the load balancer I am used to using (HAProxy). You can stuff some client identifying information into a header, cookie, or querystring before generating the request to the load balancer. Then write some rule in the load balancer config to direct traffic based on that rule. http://haproxy.1wt.eu/download/1.3/doc/configuration.txt I would be really surprised if a product like F5 does not allow this level of sophistication. If not, then I would drop it and use something more flexible. Of course nothing bars you from running a proxy like HAProxy in front of the load balancer to do some intermediary processing that allows you to take advantage of some other F5 feature. Maybe figure out what format F5 uses for it's cookies, and forge one with the request from server A. Or forge it at an intermediary proxy. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
