I've some issue with unknown traffic that seem to be referred using scripts Read about them in this thread: http://forums.digitalpoint.com/showthread.php?t=148407 Since all the referrals are coming from multiple domain but similar script URLs, e.g. www . somedomain . com /scripts/runner.php I was wondering if the code below will be able to block these kind of traffic. RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} /scripts/runner\.php [NC] RewriteRule .* - [F] Code (markup): Would appreciate any help. Thanks..
