I need to block an entire Drupal 7 site from being indexed for a while. So, I think it is best to redirect everything to 404 instead of actually deleting all my files. How can I do that?
PS: using the following code on .htaccess does not seem to work.
RewriteEngine On RewriteRule ^ - [R=404,L]

The server is nginx
