### TLS-Handshake-Start

Der Browser kommuniziert dann mit dieser IP-Adresse über **Port 443** (den HTTPS-Port).

Der erste Teil der Kommunikation besteht lediglich darin, die Verbindung zwischen dem Client und dem Server herzustellen und die zu verwendenden kryptografischen Schlüssel usw. zu vereinbaren.

### TLS Handshake Start

The browser would then communicate with that IP address on **port 443** (the HTTPS port).

The first part of the communication is just to establish the connection between the client and the server and to decide the cryptographic keys they will use, etc.

## Origin

An origin is the combination of protocol (`http`, `https`), domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`), and port (`80`, `443`, `8080`).

So, all these are different origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

## 源

源是协议（`http`，`https`）、域（`myapp.com`，`localhost`，`localhost.tiangolo.com`）以及端口（`80`、`443`、`8080`）的组合。

因此，这些都是不同的源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

即使它们都在 `localhost` 中，但是它们使用不同的协议或者端口，所以它们都是不同的「源」。

## 步骤

### TLS 握手开始

然后，浏览器将在**端口 443**（HTTPS 端口）上与该 IP 地址进行通信。

通信的第一部分只是建立客户端和服务器之间的连接并决定它们将使用的加密密钥等。

客户端和服务器之间建立 TLS 连接的过程称为 **TLS 握手**。

### 带有 SNI 扩展的 TLS

**服务器中只有一个进程**可以侦听特定 **IP 地址**的特定 **端口**。 可能有其他进程在同一 IP 地址的其他端口上侦听，但每个 IP 地址和端口组合只有一个进程。

TLS (HTTPS) 默认使用端口`443`。 这就是我们需要的端口。

由于只有一个进程可以监听此端口，因此监听端口的进程将是 **TLS 终止代理**。
