问题描述

当您没有代理IP列表时会发生什么？当使用网站加速服务，如Akamai，Google，Edgecast或CloudFront;

What happens when you don't have a list of proxy IPs? When using site acceleration services like Akamai, Google, Edgecast or CloudFront; it would always be hard to get IPs for sessions from them.

在CDN上测试我们的codeigniter应用程序时，我们注意到IP是作为CDN IP传递的，而不是

When testing our codeigniter application on a CDN, we noticed that IPs were being passed as CDN IPs and not the client IPs in the session database.

如何解决这个问题？

推荐答案

根据您使用的网络服务器，有一些模块可以从HTTP_X_FORWARDED_FOR标头或您的代理的等效端口获得真正的客户端IP地址。

Depending on the web server you use there are modules that will give you the true client IP address from the HTTP_X_FORWARDED_FOR header, or the equivalent for your proxy.

我在我的web服务器上使用Nginx CloudFlare后面，所以我使用这个： http://wiki.nginx.org/HttpRealipModule

I use Nginx on my web server behind CloudFlare so I use this: http://wiki.nginx.org/HttpRealipModule

您需要为您的网络服务器配置模块，以从CDN的正确标头获取真实的客户端IP。

You'll need to configure the module for your web server that gets the real client IP from the correct header from your CDN.
