<p>一、什么是SNI</p>
<p style="padding-left: 30px;">SNI（Server Name Indication，服务器名称指示）是TLS的一个扩展协议，该协议下，在握手过程开始时客户端将携带SNI扩展字段告诉正在连接的服务器要请求的主机名称，可解决一个服务器使用多个域名证书的问题。</p>
<p>二、什么是取源SNI</p>
<p style="padding-left: 30px;">云防御节点在与源站web服务器进行SSL握手时携带SNI扩展字段，帮助源站匹配对应证书。</p>
<p>三、开启方法</p>
<p style="padding-left: 30px;">配置入口：<a href="https://defense.yunaq.com/dns/https_page/">https://defense.yunaq.com/dns/https_page/</a></p>
<p style="padding-left: 30px;">配置方法：在状态位置点击开启即可。</p>

<p>四、SNI开启效果</p>
<p style="padding-left: 30px;">开启SNI取源后，会在TLS握手的Client Hello包中携带Server Name扩展（参考下图），帮助服务器返回正确的SSL证书。</p>
<p><img class="size-full wp-image-2459 aligncenter" src="http://help.yunaq.com/wp-content/uploads/2020/11/sni_1.png" alt="" width="962" height="536" srcset="http://help.yunaq.com/wp-content/uploads/2020/11/sni_1.png 962w, http://help.yunaq.com/wp-content/uploads/2020/11/sni_1-300x167.png 300w, http://help.yunaq.com/wp-content/uploads/2020/11/sni_1-768x428.png 768w, http://help.yunaq.com/wp-content/uploads/2020/11/sni_1-60x33.png 60w, http://help.yunaq.com/wp-content/uploads/2020/11/sni_1-150x84.png 150w" sizes="(max-width: 962px) 100vw, 962px" /></p>
<p>五、使用场景</p>
<p style="padding-left: 30px;">若源站服务器部署多个SSL证书，可开启此开关，帮助服务器匹配请求的证书。</p>
