我的网站最近几天速度变慢了。我查看了我的错误日志，发现了很多：

[Mon Sep 30 00:09:53 2013] [error] [client 66.249.66.205] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

我怎样才能找到造成这种情况的原因？

它似乎是一个围绕 index.php 的循环，除了最后一个是图像，很可能链接在我的一个页面中（不是索引）。

我正在使用 codeigniter，它是一个 mvc 框架，所有内容都通过 index.php 文件进行，因此很难理解哪里出错了。

显然它与 .htaccess 有关（在几个博客中提到过）。

这是我的 .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On

    #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]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    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.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 index.php
</IfModule> 
AddType image/x-windows-bmp bmp

我对我的 .htaccess 做了一些更改（基本上我已经在最后一个块之前删除了顶级条件），现在我得到了这个：

现在似乎img混合中有目录，但我根本没有那个目录。曾经有一个子域，我将其用于具有此地址的图像。

img.mysite.com => mysite.com/files/images/

由于一些缓慢和并发症，我不再使用它。现在我只使用图像的真实路径。

为什么我在循环中得到这个子域？我无权访问配置此服务器的人。会不会是他所做的一些配置/设置？

要防止无限循环RewriteCond，请在规则顶部添加一行，如下所示：

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

RewriteCond %{ENV:REDIRECT_STATUS} ^$通过检查第一次成功内部重定向后设置为 200的内部mod_rewrite变量来防止循环。REDIRECT_STATUS

查看您的 htaccess，我看到您使用它index.php从您的 url 中删除，但是您缺少RewriteBase，您可以像这样直接在之后添加它RewriteEngine On：

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    #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]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    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.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule>

因此，RewriteBase /如果您的应用程序/网站不在subdomain. 但是，如果是，则您可能需要在/符号后添加文件夹名称。

最后一块：

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

很可能一遍又一遍地重新注入更改的请求 URI，这可能会导致此类内部重定向错误。检查启用调试级别的错误日志以跟踪每个重定向步骤，它使事情更加明显，并会准确告诉您哪些重定向规则正在触发它。

详细说明以及如何防止重复注入，请参见：

那里概述的解决方案实际上也应该适用于您的情况。它几乎相同，即使文件名相同。

您还可以使用END 标志，而不是 L 标志：

RewriteRule ^(.*)$ index.php?/$1 [END]

使用 [END] 标志不仅会终止当前轮次的重写处理（如 [L]），而且还可以防止任何后续的重写处理在每个目录（htaccess）上下文中发生。

这不适用于由外部重定向产生的新请求。

也许它是一个假遮阳篷，但我只是清空我的 .htaccess 并再次配置永久链接。之后一切正常。

我在 drupal 根文件夹中的 .htaccess 文件中注释掉了“RewriteBase /drupal”。这个对我有用。
