Basically I want to redirect all requests to my domain to a specific page. For example, redirect all requests to page X, unless you are already on page X, in which case you should just load it. But my solutions just create an infinite loop :/
I tried...
RewriteCond %{REQUEST_URI} !=/underconstruction.html
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
RewriteCond %{REQUEST_FILENAME} !^/underconstruction.html
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
