缓存

  1. 响应
    • Last-Modified
      服务器告诉浏览器更新时间 格式为格林时间
header ("Last-Modified: " . gmdate ('r', strtotime('2018-10-22'))); 

<meta http-equiv="last-modified" content="Thu, 21 Jun 2018 06:50:50 GMT">
  • Etag
    服务器告诉浏览器保存序列号
header ("Etag:fca75d26f6dc8111a7d1b24e9debd652" )); 

<meta http-equiv="Etag" content="fca75d26f6dc8111a7d1b24e9debd652">
  • Expires
    服务器告诉浏览器过期时间 格式为格林时间
    在HTTP 1.1版开始，使用Cache-Control: max-age=秒替代
  • Cache-Control
    服务器告诉浏览器怎么控制缓存
    must-revalidate页面过期 必须服务器进行获取
    Cache-control: no-cache 禁止缓存
    Cache-Control: max-age= 生存秒数
header ("Cache-Control:max-age=5");

<meta http-equiv="cache-control" content="max-age=5">
  1. 请求
    • If-Modified-Since 请求
      浏览器告诉服务器 上一次保存的时间
      如果 If-Modified-Since 小于 Last-Modified 则重新请求
    • If-None-Match
      浏览器告诉服务器 上一次保存序列号
      如果 If-None-Match与Etag 不匹配 则重新请求
#禁止缓存
<meta http-equiv="expires" content="0">
<meta http-equiv="cache-control" content="no-cache">

压缩服务器设置

  • expires
    s 秒 m分 h小时 d天
location ~[^.]+\.(gif|jpg|jpeg)$ {
expires 30d;
}
  • gizp 压缩
gzip on;#开启
gzip_min_length 1k;#大小大于1k才开启压缩
gzip_buffers 4 16k;
#gzip_http_version 1.0;#压缩协议级别
gzip_comp_level 2;#压缩级别 1-10 数字越大压缩的越好,越耗cpu
gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;#压缩mine类型
gzip_vary off;
gzip_disable "MSIE [1-6]\.";#屏蔽IE
