这里只介绍nginx配置expires，让浏览器对静态资源进行缓存，配置如下：
location ~ .*\.(png|gif|ico|jpg|jpeg|eot|svg|svgz|mp4|ogg|ogv|webm|ttf|woff)$ {
root F:\apache-tomcat-web\ROOT;
expires 7d;
}
location ~ .*\.(js|css)$ {
root F:\apache-tomcat-web\ROOT;
expires 7d;
}
不对html进行缓存
location ~ .*\.(htm|html)$ {
root F:\apache-tomcat-web\ROOT;
add_header Cache-Control "private, no-store, no-cache, must-revalidate, proxy-revalidate";
}
