Question : How to prevent bandwith leeching on content?

i don't have specific download which people are leeching, but I have a database which produces pages which people are leeching and stealing my bandwidth.

I think I need to stop people accessing a certain amount of pages per day.

But I don't want to stop google bot or the yahoo bot.

I don't mind paying a small amount for commercial protection, $50 perhaps.

But I think the solution need to be PHP / MySQL based, I think.

Help ?

Perhaps try using a .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://www.yoursite.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.yoursite.com$ [NC]
RewriteRule .*\.(.*)$ http://www.yoursite.com/ [R,NC]
