Nginx提高安全与性能的最好配置详解

# 不要将Nginx版本号在错误页面或服务器头部中显示
server_tokens off;

#不允许页面从框架frame 或 iframe中显示，这样能避免clickjacking
# http://en.wikipedia.org/wiki/Clickjacking
# 如果你允许[i]frames, 你能使用SAMEORIGIN 或在ALLOW-FROM中设置你的允许的url
# https://developer.mozilla.org/en-US/docs/HTTP/X-Frame-Options
add_header X-Frame-Options SAMEORIGIN;

#当你的网站是用户提供的内容比如博客论坛等，使用 X-Content-Type-Options: nosniff 头部,
# 这是为了失效某些浏览器的内容类型探嗅
