Question

由于ssl重定向，我经历了长达12秒的等待时间。我尝试了一些东西，似乎无法找出原因。使用“www.thesoapopera.com”时似乎是最糟糕的。

www.thesoapopera.com将近12秒： https://tools.pingdom.com/#!/BBsdZ/www.thesoapopera.com

1.13秒，完整https://www.thesoapopera.com： https://tools.pingdom.com/#!/cPx3LD/https://www.thesoapopera.com

几乎背靠背测试，网站加载时间延长10秒！这是我的htaccess文件：

Answer 1

如果直接访问https://站点，则尚未发送cookie且响应相对较小：仅为20KByte。在访问http://的情况下，此网站会提供一个Cookie，然后在重定向到https://网站时发送该Cookie会导致121 KByte的响应量大得多。

我的猜测是，如果发送会话cookie，应用程序逻辑会执行大量数据库查找，这会导致创建响应所需的时间较长，也会导致不同的更大内容。此外，您可以看到https://版本只会产生50个请求，而http://版本会产生77个请求，即会完成更多请求（可能是因为提供的内容不同），这会影响性能

尝试将所有重写分组到一个单独的IfModule部分，当然首先保持SSL重定向，但是correct syntax：

RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

非常慢的https重定向 - 加载时间增加10秒
