Hello Willy,
Once again, thanks for clarifications and let me ask one more question regarding the products which allow this functionality. Could you please name some of them? Are they pure software-only solutions as HAProxy, or the products you mentioned below are a complex solutions which consist of hardware and software? Loking forward for your reply, Victor.

Also keep in mind that HTTP spec absolutely forbids doing this because replying non-idempotent requests can have important impacts. And yes, I'm aware that some products do this anyway, which might be the reason why a coworker once received two books when he ordered one on a site. Regards, Willy
