Here’s another similar trick, using mod_rewrite. You can use it to redirect IP’s to a certain page on your site or even another site.

RewriteCond %{REQUEST_URI} !=/goaway.txt
RewriteCond %{REMOTE_ADDR} =aaa.aaa.aaa.aaa
RewriteRule .* /goaway.txt [R,L]

You can do classes as well, using regular expressions:

RewriteCond %{REQUEST_URI} !=/goaway.txt
RewriteCond %{REMOTE_ADDR} ^aaa.aaa.aaa.
RewriteRule .* /goaway.txt [R,L]

I use this whenever I upgrade a website and I don’t want anybody but me roaming the site for half an hour. Use something like whatismyip.org to find your current IP:

RewriteCond %{REQUEST_URI} !=/maintenance.txt
RewriteCond %{REMOTE_ADDR} !=your.current.ip.here
RewriteRule .* /maintenance.txt [R,L]

Just make sure to clear these lines when you’re done.

Thank you
