禁止远端WWW服务支持TRACE请求
TRACE_Method是HTTP（超文本传输）协议定义的一种协议调试方法，该方法会使服务器原样返回任意客户端请求的任何内容。
TRACE和TRACK是用来调试web服务器连接的HTTP方式。支持该方式的服务器存在跨站脚本漏洞，通常在描述各种浏览器缺陷的时候，把"Cross-Site-Tracing"简称为XST。攻击者可以利用此漏洞欺骗合法用户并得到他们的私人信息。
如何关闭Apache的TRACE请求
虚拟主机用户可以在.htaccess文件中添加如下代码过滤TRACE请求:
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
RewriteRule .* - [F]
服务器用户在httpd.conf尾部添加如下指令后重启apache即可:
TraceEnable off
