The IP Deny Manager enables you to block access to your web site from specific IP addresses. This is useful to remove nuisance surfers who use a large amount of bandwidth or to prevent hotlinking to your site (refer to HotLink Prevention for more information about hotlinking). You could also use this feature if you are an e-commerce site and have a large amount of fraud from a particluar IP or want to ban someone from a forum or otherwise using your site.
