我已经有一个使用 CodeIgniter 1.7 的客户网站大约 6 年了，没有任何问题。但是，最近我将 CodeIgniter 框架更新到 2.1.1，现在 .htaccess 出现了问题。我已经在日志中确认它没有到达我的控制器，所以我相信这纯粹是一个 .htaccess 问题。
我有几个典型的 URL 模式：
mysite.com/<page name here>, i.e. mysite.com/faq
mysite.com/admin/<action here>, i.e. mysite.com/admin/login
我.htaccess目前是：
RewriteEngine On
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/page/id/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(admin/*)$ index.php/$1 [L]
现在，应该很明显，mysite.com/faq应该重写为mysite.com/page/id/faq，但它正在抛出 404 。
只是要mysite.com成功加载默认控制器，在这种情况下是主页或等效于mysite.com/home. 所有管理员网址都运行良好。mysite.com/page/id/<page name here>也工作得很好。
只是为了比较，在.htaccess我升级 CodeIgniter 之前已经运行了 6 年的原始版本是：
RewriteRule ^((images|styles|scripts|documents)/*.*)$ $1 [L]
RewriteRule ^(admin/*)$ index.php/$1 [L]
RewriteRule ^([a-zA-Z0-9]+)$ page/id/$1
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ index.php/$1 [L]
这个原始的行为与我目前在上面尝试使用的行为完全相同。原文的重写日志如下：

实际的升级过程只是在 CodeIgniter 框架上，并将文件重新组织到单独的application和system文件夹中，除了升级过程中所需的最小更改之外，我没有触及任何实际的自定义代码。
我已经尝试了大约十亿个不同的.htaccess命令组合，试图让这个东西工作，但无法让“正常”页面和管理页面都使用相同的配置正确加载。最终我的问题是，为什么升级 CodeIgniter 会神奇地破坏 URL 重写，但我很乐意让它再次工作。
有人有建议吗？我希望对此有另一种看法。
