Question

我正在尝试将一条简单的301规则添加到codeigniter网站的.htaccess文件中。

redirect 301 /newsletter http://sub.domain.com/newsletters/may2010

当我访问http://sub.domain.com/newsletter时，重定向会转到

http://sub.domain.com/newsletters/may2010/?/newsletter

我不确定？/时事通讯的来源。完整的.htaccess文件：

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /    

    redirect 301 /newsletter http://sub.domain.com/newsletters/may2010

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>



<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
</IfModule>

我该如何解决这个问题？

嘿，这是Apache在你身上扯出一个偷偷摸摸的处理顺序技巧。事实证明，将Rewrite命令放在文件顶部这一事实并不意味着它实际上是先执行的。相反，首先运行mod_rewrite，然后运行mod_alias（负责处理您的Rewrite）。

这导致以下转换，每mod_rewrite：

newsletter --> index.php?/newsletter

mod_rewrite愉快地将查询字符串设置为?/newsletter，但由于您没有指定PT标记，不通过重写的网址{ {1}}到index.php。因此，mod_alias仍会看到mod_alias路径，将其重定向到/newsleter，并将（现在已更改的）查询字符串http://sub.domain.com/newsletters/may2010附加到最后以加密交易。有趣的东西，对吗？

无论如何，针对此方案的快速修复方法是忽略仅?/newsletter的请求：

newsletter

htaccess 301重定向无法正常工作
