A customer has a Webserver (Apache 2) with a custom system that allow users to create his own websites. Like a Site Builder.
All websites images are store in a single directoty calles website_imgs, and each web site points the img links to www.isp.com/website_imgs/uploaded_image.jpg
But a lot of customers are linking these images to orkut profiles, etc.. causing a lot of bandwitdht usage.
I see a lot of tutorials to block Hotlinking and only allow to specific referers. But i can´t do this because a have more than 100.000 authorized referrals.
Is there a way to allow link from a ip range ?
