使用 ISAPI Filter 实现的限制 IIS 多线程访问程序。

主要应用在下载系统，或者使用 IIS 做的流媒体点播系统中，稍加修改可以使其具有认证功能。在程序中已经对 用户认证 事件做了直接返回的处理。



使用本 Filter 可以很容易的获得服务器的连接数，从而可以实现多个服务器的负载平衡(可以把请求分发到连接较少的一个服务器上)。



可以对访问的有效控制，可以自定义无限制用户IP，限制用户的IP。

从而可以实现对某个IP的限制数不限制，或者对某个IP的封杀-Restrictions on the use of ISAPI Filter to achieve IIS multi-threaded access to the program. Main application in the download system, or use IIS to do the streaming media on-demand system, slightly modified to give it authentication. In the user authentication process has already done a direct return to processing. Use the Filter can be easily access the server connections, allowing multiple servers to achieve load balancing (which can be distributed to the request to connect to a fewer server). Access can be effectively controlled, you can customize unlimited users IP, restrictions on the user' s IP. Which can be achieved on a certain IP restriction does not limit the number of, or an IP-block
