为Request.ServerVariables [＆QUOT; REMOTE_ADDR＆QUOT]足够可靠吗？ [英] Is Request.ServerVariables["REMOTE_ADDR"] reliable enough?

问题描述

目前我使用Request.ServerVariables [REMOTE_ADDR]从客户端得到IP地址。

Currently I am using Request.ServerVariables["REMOTE_ADDR"] to get the IP from the client.

什么保证我得到调用此方法时。或者我应该看看在其他ServerVariables呢？

What guarantees I get when calling this Method. Or should I look in other ServerVariables as well?

推荐答案

上找到这里检索客户端的IP地址，一些非常整齐的信息。

从本质上讲，你应该也注意 Request.ServerVariables（HTTP_X_FORWARDED_FOR）为好。这有助于确定实际的IP地址，如果最终用户是通过代理，而 REMOTE_ADDR 属性，除非它是一个匿名代理是代理服务器的地址...在这种情况下，你仍然只是得到了代理地址。

Essentially, you should probably also pay attention to the Request.ServerVariables("HTTP_X_FORWARDED_FOR") as well. This helps to identify the actual IP address if the end user is going through a proxy whereas the REMOTE_ADDR attribute would be the address of the proxy...unless it is an anonymous proxy in which case, you would still just get the proxy address.
