How to make a redirect to one page?

Question

htaccess

Hello, the idea is this: I want to make a stub page "the site is under construction". It is necessary to make sure that from all pages there is a redirect to one single (stub file). How to do it?

Answer 1

RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !page.html
RewriteRule ^.*$ /page.html [R=302,L]

Instead of page.html, substitute a page with a stub
