我的应用程序中有这样的 .htaccess 文件。（仅为安全示例）
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /app_folder/
#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?/$1 [L]
#Checks to
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ 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>
在（Rewritebase /app_folder/）中，如果我的应用程序在服务器中，我将在 app_folder 名称中放入什么？我应该将主机名放在 app_folder 中吗？例如
Rewritebase /http://example.com/
因为我的 app_folder 现在是我的 webroot。我是使用 CentOS 在服务器中上传我的 HMVC codeigniter 设置的新手。
