可以使用VirtualWall防盗链专家
“防盗链专家”是一个为微软 IIS 服务器编写的一款优秀的防盗链软件。 该程序免费提供给个人使用，它能帮助您保护服务器上的资源不被盗链下载。 每 10000 个请求处理仅需 500 毫秒。 特有下载线程限制，您可以指定每个用户的最大下载线程，反击一切霸道下载行为。 甚至您可以指定单个线程的下载速度，有效保证服务器稳定运行。 本程序附带的动态链接强制转换静态链接功能免费提供给大家使用，无须购买。 商业版本无流量限制，终身免费升级。
流媒体是一种比较特殊的文件，他在向服务器发请求的时候是没有 Referer 信息的。所以单纯从 Referer 上是不好做防盗的。
虽然流媒体文件的请求信息里没有 Referer 信息，但是 Cookie 信息是有的。防盗链专家 V2.0 以后版本开始使用 Cookie 验证技术， 在每个请求里进行特殊的 Cookie 处理，所有处理都是在服务端进行的，所以你无须改造任何页面，也无须包含任何头文件，纯静态 HTML 页面也能做流媒体防盗链。
您只需要简单地通过配置管理工具将被保护的流媒体文件的扩展名填写到保护列表即可。
直接将 VirtualWall.dll 加载到您的这个站点即可，无须特殊配置
在 Windows 2003 IIS6 下，需要特殊的权限 IIS Filter 才能被加载。在 IIS6 被安装的时候，IIS6 安装程序创建了一个工作组 IIS_WPG（IIS 工作进程组），起成员大概有 Local Service，Network Service 等。只要给予 IIS Filter 文件所在目录 IIS_WPG 权限 IIS Filter 即可被加载。
注意：
IIS6 不会在重新启动后立即加载 VirtualWall.dll，它会在第一次接受请求的处理时加载。所以重新启动后你不会立即看到 VirtualWall.dll 所在目录下有 cfg.ini 配置文件生成。所以您需要：打开浏览器，访问一下捆绑在这个加载了 VirtualWall.dll 的站点（任意页面都可以）即可看见 cfg.ini 生成。【转自bbs.bitsCN.com】
