* **默认情况下**，这意味着你**每个 IP 地址只能拥有一个 HTTPS 证书**。
     * 无论你的服务器有多大，或者服务器上的每个应用程序有多小。
     * 不过，对此有一个**解决方案**。
* **TLS** 协议（在 HTTP 之下的TCP 层处理加密的协议）有一个**扩展**，称为 **<a href="https://en.wikipedia.org/wiki/Server_Name_Indication" class="external-link" target="_blank"><abbr title="服务器名称指示">SNI</abbr></a>**。
     * SNI 扩展允许一台服务器（具有 **单个 IP 地址**）拥有 **多个 HTTPS 证书** 并提供 **多个 HTTPS 域名/应用程序**。

    didn't have it.
 *  Fix: Explicitly specify the remote server name when making HTTPS connections on Android 5. In
    4.3.0 we introduced a regression where server name indication (SNI) was broken on Android 5.


## Version 4.3.0

 *  Fix: Degrade HTTP/2 connections after a timeout. When an HTTP/2 stream times out it may impact

 *  New: `mockwebserver3.MockResponse` is now immutable, with a `Builder`.

 *  New: `mockwebserver3.RecordedRequest.handshakeServerNames` returns the SNI (Server Name
    Indication) attribute from the TLS handshake.

 *  Upgrade: [Kotlin 1.9.21][kotlin_1_9_21].

 *  Upgrade: [Okio 3.7.0][okio_3_7_0].

It is then truncated to fit in the result type's size.
For example, if <code>v := uint16(0x10F0)</code>, then <code>uint32(int8(v)) == 0xFFFFFFF0</code>.
The conversion always yields a valid value; there is no indication of overflow.

When converting a floating-point number to an integer, the fraction is discarded
