## 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)

So we have a dedicated thread for every socket that just reads frames and dispatches them.

The reader thread must never run application-layer code. Otherwise one slow stream can hold up the entire connection.

  // Optional: confirm that your app made the HTTP requests you were expecting.
  val request1 = server.takeRequest()
  assertEquals("/v1/chat/messages/", request1.url.encodedPath)
  assertNotNull(request1.headers["Authorization"])

  val request2 = server.takeRequest()
  assertEquals("/v1/chat/messages/2", request2.url.encodedPath)

  val request3 = server.takeRequest()
