Selector & rule

According to your HTTP request headers, selectors and rules are used to route your requests.

Selector is your first route, It is coarser grained, for example, at the module level.

Rule is your second route and what do you think your request should do. For example a method level in a module.

The selector and the rule match only once, and the match is returned. So the coarsest granularity should be sorted last.

When user have changed the configuration in the background management, ShenYu wiil dynamically updates its cache by listening to the ZooKeeper node, WebSocket push, HTTP longPull.
