nginx配置http强缓存

强缓存与协商缓存概念：

如何配置强缓存：

server {

listen       80;
server_name  tirion.me www.tirion.me;

# note that these lines are originally from the "location /" block
root   /home/www/wordpress;
index index.php index.html index.htm;

location / {
    try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
    root /usr/share/nginx/html;
}

location ~ \.php$ {
    try_files $uri =404;
    fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}
# 配置 HTTP 强缓存静态文件，通过 Response Header 头返回
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css)$ {
    expires 3d;
}

}
