Question

How can I modify this htaccess file to exclude visitors with 2 different Ip addresses from being sent to the offline page? Thanks.

RewriteEngine on
RewriteCond %{REQUEST_URI} !/offline.php$
RewriteRule .* /offline.php [L]

Answer 1

This will do the job:

RewriteEngine on
RewriteCond %{REQUEST_URI} !/offline.php$
RewriteCond %{REMOTE_ADDR} !^(192\.168\.0\.2|192\.168\.0\.9)
RewriteRule .* /offline.php [L]

Just put your own IPs.
