Custom IRule In this paper, we implement a custom load balancing strategy - consistent hash through IRule interface. The principle of consistent hash is not the focus of this paper. If you don't understand it, you can read this article Principle and implementation of consistent hash algorithm , it's very good. Consistent hash is widely used no ...
