代码如下:
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 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] # redirect to boutique (with any trailing path) rewritecond %{http_host} !^www.
