.htaccess - htaccess : how to redirect all pages to a holding page

Question

在我们安装第二台服务器的同时，我必须关闭一个站点大约半个小时。使用 .htaccess，如何将任何对 domain.com 的请求重定向到 domain.com/holding_page.php？

Answer 1

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !/holding_page.php$ 

RewriteRule $ /holding_page.php$l [R=307,L]

使用 307(感谢 Piskvor!)而不是 302 - 307 means :

The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests.
