请求超出了10个内部重定向的限制

Question

我的网站在最近几天放慢了速度.我查看了我的错误日志,发现了很多这些:

我怎样才能找到导致这种情况的原因？

它似乎是一个围绕index.php的循环,除了最后一个是图像,最有可能在我的一个页面(而不是索引)中链接.

我正在使用codeigniter,这是一个mvc框架,所有内容都通过index.php文件,因此有点难以理解它出错的地方.

显然它与.htaccess有关(在几个博客中已经提到过).

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>

我对.htaccess进行了一些更改(基本上我已经删除了最后一个块之前的顶级条件),现在我得到了这个:

现在似乎img混合中有目录,但我根本没有该目录.曾经有一个子域我用于这个地址的图像.

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

由于一些缓慢和并发症,我不再使用它了.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名？我没有权限配置此服务器的人.可能是他做过的配置/设置吗？

Answer 1

要防止无限循环RewriteCond,请在规则顶部添加额外的行,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REDIRECT_STATUS来阻止循环.

参考:Apache mod_rewrite简介

Answer 2

查看您的 htaccess，我发现您使用它index.php从您的网址中删除，但您缺少RewriteBase，您可以直接在之后添加它，RewriteEngine On如下所示：

<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，那么您可能需要在/符号后面添加文件夹名称。
