HTTP 301重定向性能

我有一个网站“www.example.net”HTTP 301重定向性能

但我注意到，当我进入“example.net”（到浏览器），我会先收到一个301，这将正确重定向到网站。

我的问题是它需要6 - 17秒才会被重定向。

我想知道的是，如此广泛的操作以及如何解决这个问题的原因是什么？

其他信息网站是一个Apache服务器上的Wordpress网站。

编辑 的.htaccess

应该以毫秒为单位发生。你的htaccess规则内容是什么？ – briansol 2014-10-02 18:50:39

你的意思是什么在我的htaccess文件？ – PrivatMamtora 2014-10-02 19:08:42

这谷歌结果似乎相关：https://wordpress.org/support/topic/painfully-slow-301-redirect-from-htaccess-trailing-slash – xpa1492 2014-10-03 04:07:07

您有非www重定向到www没有htaccess的规则。如果它正在重定向，那是因为WordPress正在以脚本方式处理它并执行重定向。它曾经到达那里之前

陷阱吧...

变化的最后一条规则：

<IfModule mod_rewrite.c> 
    RewriteEngine On 
    RewriteBase/
    RewriteRule ^index\.php$ - [L] 
    RewriteCond %{REQUEST_FILENAME} !-f 
    RewriteCond %{REQUEST_FILENAME} !-d 
    RewriteRule . /index.php [L] 
</IfModule>

到

<IfModule mod_rewrite.c> 
    RewriteEngine On 
    RewriteBase/
    RewriteCond %{HTTP_HOST} ^yourdomain.com [NC] 
    RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [L,R=301] 
    RewriteRule ^index\.php$ - [L] 
    RewriteCond %{REQUEST_FILENAME} !-f 
    RewriteCond %{REQUEST_FILENAME} !-d 
    RewriteRule . /index.php [L] 
</IfModule>
