Request exceeded the limit of 10 internal redirects
提问by max
My website has been slowed down a little last couple of days. I've looked into my error log and found lots of these:
我的网站最近几天变慢了。我查看了我的错误日志，发现了很多这些：

How can I find what is causing this?
我怎样才能找到导致这种情况的原因？
It seems a loop around index.php, with the exception of the last one which is an image, most likely linked within one of my pages (not index).
这似乎是一个围绕 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（不是索引）中。
I'm using codeigniter, which is a mvc framework and everything goes trough the index.php file, so it's a bit harder to understand where it goes wrong.
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。
Apparently it has something to do with .htaccess (it's been mentioned in couple of blogs).
显然它与 .htaccess 有关（在几个博客中提到过）。
Here is my .htaccess
这是我的 .htaccess
<IfModule mod_rewrite.c>

I did some changes to my .htaccess (basically I've removed to top conditions before the last block) and now I get this:
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移除了最高条件），现在我得到了这个：

Now it seems there is the imgdirectory in the mix, but I dont have that directory at all. There used to be a subdomain which I used for images with this address.
现在似乎img混合中有该目录，但我根本没有该目录。曾经有一个子域，我用于具有此地址的图像。
img.mysite.com => mysite.com/files/images/
I don't use it anymore because of some slowness and complications. Now I just use the real path to images.
我不再使用它了，因为有些缓慢和复杂。现在我只使用图像的真实路径。
Why do i get this subdomain in the loop? I don't have access to the guy who configured this server. Could it be some config / setting that he has done?
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。可能是他所做的一些配置/设置？
回答by anubhava
To prevent infinite looping add an extra RewriteCondline on top of your rule like this:
为了防止无限循环RewriteCond，在您的规则之上添加额外的一行，如下所示：
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/ [L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$prevents looping by checking an internal mod_rewritevariable REDIRECT_STATUSwhich is set to 200 after first successful internal redirect.
RewriteCond %{ENV:REDIRECT_STATUS} ^$通过检查在第一次成功内部重定向后设置为 200的内部mod_rewrite变量REDIRECT_STATUS来防止循环。

The last block:
最后一块：
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/ [L]
Is most likely re-injecting a changed request URI over and over again which could cause such an internal redirect error. Check the error log with debugging level enabled to trace each redirect step, it makes things much more visible and will tell you exactly which redirect rules are triggering it.
很可能一遍又一遍地重新注入已更改的请求 URI，这可能会导致此类内部重定向错误。在启用调试级别的情况下检查错误日志以跟踪每个重定向步骤，它使事情更加明显，并且会确切地告诉您哪些重定向规则正在触发它。
For a detailed description and how to prevent the re-injection, please see:
有关详细说明以及如何防止重新注入，请参阅：
The solution outlined thereactually should do it in your case as well. It's pretty much the same, even the file-names are identical.

Looking to your htaccess I see that you use it to remove index.phpfrom your url, but you are missing the RewriteBase, you can add it after the RewriteEngine Ondirectly like this:
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RewriteEngine On像这样直接在 之后添加它：

RewriteBase /

#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?/ [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.*

RewriteCond %{REQUEST_FILENAME} !-f

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

So, RewriteBase /will be valid if your application/website is not on a subdomain. However, if it is then you might need to add the folder name after the /symbol.
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。

Maybe it is a dummie awnser, but I just empty my .htaccess and configure permalinks again. Everything works after that.
也许它是一个虚拟的 awnser，但我只是清空了我的 .htaccess 并再次配置了永久链接。之后一切正常。
回答by mikiqex
You can also use the END flag, instead of the L flag:
您还可以使用END 标志，而不是 L 标志：
RewriteRule ^(.*)$ index.php?/ [END]
Using the [END] flag terminates not only the current round of rewrite processing (like [L]) but also prevents any subsequent rewrite processing from occurring in per-directory (htaccess) context.
This does not apply to new requests resulting from external redirects.
使用 [END] 标志不仅可以终止当前轮次的重写处理（如 [L]），还可以防止在每个目录 (htaccess) 上下文中发生任何后续的重写处理。
这不适用于由外部重定向产生的新请求。

I commented out the "RewriteBase /drupal" in my .htaccess file? present in drupal root folder. It works for me.
