推荐答案

我能想到的唯一方法是限制您的Web应用程序只能使用特定范围的IP地址.

获取客户端的IP地址，如果它不在您的允许"列表中，则用漂亮的页面说明原因，拒绝用户.

容易做到:

The only way I can think of is to restrict your web app to only work with a specific range of IP addresses.

Get the IP address of the client, and if it isn''t in your "permitted" list, reject the user with a pretty page explaining why.

Easy to do:

string ClientIP = Request.ServerVariables["REMOTE_ADDR"];

跟踪IPAddress，在某些文件或数据库中列出列入黑名单的IPAddress.

如果在数据库或文件中保存的列表中找到站点，请在站点加载时检查用户的IPAddress.

将用户发送到显示消息您的机器无权查看此站点"的页面.

就是这样，希望你明白我的意思...:)

Track the IPAddress, Make a list of blacklisted IPAddress in some file or database.

Check IPAddress of user when the site loads if it is found in the list you kept in DB or file.

Send user to some page showing message "your machine is not authorized to view this site".

Thats it, Hope you got my point...:)
