codeigniter 用.htcaccess做动态二级域名解析

 

今天将服务器php版本升到了5.4.4，然后将之前的一个项目改用apache,动态二级转向用.htcaccess，共享一下

AuthName "yousite Website Coming Soon..."  //如果你想给你的网站加个权限访问
AuthType Basic 
AuthUserFile D:/xxx/.htpasswd  #如果你想设置密码访问 如何生成.htpasswd可以访问 http://www.htaccesstools.com/htpasswd-generator/
#AuthGroupFile /dev/null 
require valid-user

    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.* 
    RewriteRule ^(.*)$ /index.php?/$1 [L]
