+## 想法
+暴露一些端点，提供一些功能。
+
+1. http-cache
+
+2. RateLimiter
+
+3. ... ...
+
+### 不是用网关，单体应用
+拦截器处理，基于 redis 的 cache 时间或者 RateLimiter处理。
+
+结构：serviceName:http-cache:/user/1?queryString If-Modified-Since
+结构：serviceName:RateLimiter:/user/1 99
+
+### 使用网关
+将端点信息存储到 redis 里，供 网关使用。
+结构：serviceName:http-cache:endpoint:/user/{id}  100s
+
+结构：serviceName:RateLimiter:endpoint:/user/{id} 100/s
+
