jagerzhang opened a new issue #5453: URL: https://github.com/apache/apisix/issues/5453
### Issue description Nginx 的 proxy-cache 可以动态设置TTL，比如： ``` proxy_cache_valid 200 1m; # 响应码为200的缓存1分钟 proxy_cache_valid 304 1h; # 响应码为304的缓存1小时 ... ``` 但是APISIX 文档提到：`The cache expiration time cannot be configured dynamically. The expiration time can only be set by the upstream response header Expires or Cache-Control, and the default cache expiration time is 10s if there is no Expires or Cache-Control in the upstream response header` 意思是完全看后端的过期设置来定，否则就按config.yml 默认的cache_ttl，感觉不是那么灵活，是否可以开放下，让我们可以在路由里面自行设置缓存TTL，并可以强制缓存（Nginx的 proxy-cache 还支持proxy_ignore_headers 忽略后端缓存申明...） ### Environment - apisix version (cmd: `apisix version`): 2.10.0 -- This is an automated message from the Apache Git Service.
