代碼如下:

AuthName "yousite Website Coming Soon..." //如果你想給你的網站加個權限訪問
AuthType Basic
AuthUserFile D:/xxx/.htpasswd #如果你想設置密碼訪問 如何生成.htpasswd可以訪問 http://www.htaccesstools.com/htpasswd-generator/
#AuthGroupFile /dev/null
require valid-user

<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]


<IfModule mod_proxy.c>
# Redirect to boutique (with any trailing path)
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+).yousite.com(.*)$ [NC]
RewriteRule ^(.*)$ http://www.yousite.com/boutique/$1$2 [P,L]
</IfModule>

<IfModule !mod_proxy.c>
# Redirect to boutique (with any trailing path)
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+).yousite.com(.*)$ [NC]
RewriteRule ^(.*)$ http://www.yousite.com/boutique/%1/$1 [R=301,L]
</IfModule>

## Otherwise, force www;
RewriteCond %{HTTP_HOST} ^yousite.com$ [NC]
RewriteRule ^(.*)$ http://www.yousite.com/$1 [R=301,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.

ErrorDocument 404 /index.php
</IfModule>
