## 代理转发请求头 { #proxy-forwarded-headers }

当使用代理来处理 HTTPS 时，你的**应用服务器**（例如通过 FastAPI CLI 运行的 Uvicorn）对 HTTPS 过程并不了解，它只通过纯 HTTP 与 **TLS 终止代理**通信。

这个**代理**通常会在将请求转发给**应用服务器**之前，临时设置一些 HTTP 请求头，以便让应用服务器知道该请求是由代理**转发**过来的。

/// note | 技术细节

这些代理请求头包括：

* [X-Forwarded-For](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-For)

    assert response.headers["WWW-Authenticate"] == "APIKey"

### Service
- Inject behaviors (Bhv) for data access
- Use `OptionalEntity<T>` for nullable returns
- Plain classes (no extends/implements)

### Helper
- Stateless utility classes
- Access via `ComponentUtil.getXyzHelper()`
- Named with "Helper" suffix

### DBFlute Generated Code
