Forbid the site's browsing to anyone but not to me

Do you use an .htaccess file? Here's the code from mine I use for when I put the site into maintenance mode. Hopefully it will help you.

Code:

#RewriteEngine On
#RewriteCond %{REQUEST_URI} !^/maintenance_mode.php
#RewriteCond %{REMOTE_HOST} !^123\.45\.67\.89
#RewriteRule $ /maintenance_mode.php [NC,L]

Just use your own IP address, and make sure you have a file in your Web root called maintenance_mode.php (with a message to your users), then uncomment those lines.
