Yes it's exactly that. It's possible to have up to 4 stick methods at once from what I recall. So it's possible to learn the response using a "stick store-response" rule and match in the request using "stick match". > This would be a great and wondrous thing for cookie-less clients and > decoupled servers - not to mention it may be a unique feature among > existing load balancing products. I'm sure some other products are able to do that using a bit of scripting, and that should be possible with products from Zeus or F5 which are particular known for their scripting abilities. When we implement it in haproxy, a few other products will be able to do it too :-) I'll see what I can come up with. After a bit of thinking, I'm not even sure it's useful to be able to configure the header name, as I don't expect this feature to be used on anything other than Location. Regards, Willy
