本帖200分，共500分，求解决NDIS拦截HTTP数据包问题。
当前情况：
修改扩展XPASSTHRU 程序，在服务器上拦截指定域名（未备案），我在PtReceivePacket解析到指定的域名后，就发送我的
拦截页面数据包，发送成功后客户端成功显示我的拦截页面，然后问题来了，服务端一直在重发ACK同步数据包。
为了解决这个问题，我在PtReceivePacket 的PEDEING里和PtSendComplete 里加上了像服务端发送RESET数据包的函数，然后
在PtSendComplete 的NdisFreeBuffer 蓝屏，注释掉NdisFreeBuffer 不蓝屏，可是还是不挺的重发ACK包，而且我没有抓取
到我往服务器发送的RESET包，头晕了，求帮助，需要看代码可以给下邮箱或QQ，我的QQ：116988566
PtSendComplete PtReceivePacket 函数如下：
- C/C++ code
