「代理」會攔截原始用戶端請求，並在將其轉交給「應用伺服器」之前加入特殊的「轉發」標頭（`X-Forwarded-*`）。

這些標頭會保留原始請求中原本會遺失的資訊：

* X-Forwarded-For：原始用戶端的 IP 位址
* X-Forwarded-Proto：原始協定（`https`）

* StatefulSet will now fill the `hostname` and `subdomain` fields if they're empty on existing Pods it owns. This allows it to self-correct the issue where StatefulSet Pod DNS entries disappear after upgrading to v1.7.x ([#48327](https://github.com/kubernetes/kubernetes/pull/48327)).
