Can we use rules across multiple requests? / rules规则可以跨请求生效吗？

Sometimes we want to get info due to multiple request, not only single request. Currently rules are only effect for single request process, can we support rules across multiple requests? e.g.: I want to track multiple requests and process them as a whole.

想问下rules能支持跨请求生效的操作吗？现在的rules都只支持对单个请求生效。
例如想要对追踪多个http请求，并把他们作为一个整体来应用rules处理。

No files or tests are named. Start by locating the current rules-processing entry point and tracing its single-request lifecycle; then determine how requests would be grouped and how state would persist across them. Done requires agreed semantics for grouping, completion, and rule application, plus coverage for a multi-request sequence.
