Introduction

HotlinkBlocker is an IIS plug-in that will protect your web site from bad people stealing your traffic by directly linking to the content on your server. If you have an image collection, video or document archives, Flash games or any other downloadable content HotlinkBlocker is a right product for you.

After installing HotlinkBlocker your site will continue working as before, all search engines and backward links will still be valid, all user’s favorites will remain valid. But if someone tries to embed your stuff directly on their site, they will only see an error message or your site’s logo. You can save tons of traffic and thus the money. You can even turn these hotlinks into real visitors by redirecting hotlink request to your site’s homepage.

HotlinkBlocker provide three different method of protection that you can choose from. Simplest method can be applied to your site with Zero Administration Work. The most comprehensive method gives you unbreakable protection technology based on a cryptographic signing and link expiration. As a small bonus you can use HotlinkBlocker to restrict unauthorized access to the files.

Here is a brief description of all three methods:

LINK:
 This is a most comprehensive and powerful protection method. In this mode HotlinkBlocker will change all links to the protected content on your site by adding special cryptographic signature to every link. You set an expiration timeout so every link will become invalid for instance in 30 minutes after it was requested. LINK method is not sensitive to HTTP Referer modifications, disabled cookies or JavaScripts in user’s browsers and it is absolutely reliable. Any type of files can be protected, including streaming media and embedded content.

REFERER:
Simply checks HTTP Referer header and reject all requests to the protected content from unknown sites. Support white and black lists based on Referer and User-Agent values to allow friendly sites requests and protect against some ugly hacks. This method does not require any configuration or modification to your site and it is a convenient way to protect image archives.

REDIRECT:
Checks Referer header value, but issue a redirect to a temporary signed link instead of returning content. It may be hard to understand the theory of this method, but the only thing you need to know that it provide moderate protection level to protect some embedded content that cannot be protected by a REFERER method - content like PDF files, Flash and Media Player movies, sounds and so on. Just as method above you don’t have to change anything, only enable HotlinkBlocker and specify a protection folder.
