Anti-leech is an IIS add-on that stops unauthorized direct linking to your server's resources, thus safeguarding your website from traffickers. Suitable for safeguarding image collections, videos, software, and document archives and flash games.

If you're a webmaster, you've probably heard of the problem of hotlinking or file leeching, which involves external linking, remote linking, deep linking or direct linking that leads to your site's bandwidth being stolen by bandwidth bandits. However, with the IIS Anti-leech Sniffer Dog, you can now put an end to this problem.
This IIS plug-in is specifically designed to counter hotlink bandwidth theft and provide webmasters with the ultimate solution to the problem. This software product can help you to protect your image collection, video, software, document archives, Flash games or any other downloadable resource from being stolen by unauthorized users.
After installing the UISD, your site will continue to function normally without any disruption to your search engine rankings, backward links or favorites. But, in case an unauthorized user tries to embed your stuff directly on their site, they will only see an error message or your site's logo and not be able to steal your bandwidth.
This product can save you a lot of money by preventing hotlinks from consuming your traffic. You can even redirect hotlink requests to your site's homepage and convert these hotlinks into real visitors. The IIS Anti-leech Sniffer Dog is coded in C++, which is an extremely effective programming language, that performs especially well in multi-thread IIS5 and IIS6.
The software is reliable and occupies only a small amount of CPU, making it an excellent choice for webmasters who are tired of dealing with hotlink bandwidth theft. Unlike other options that use C# ASP scripts, UISD was designed with high load capability in mind from the beginning, making it a more effective product overall. It's a great solution for those in search of a reliable and efficient hotlink protection tool.
