配置静态元素过期时间

浏览器访问网站的图片时会把静态的文件缓存在本地电脑里，这样下次再访问时就不用去远程下载
增加配置 <IfMondule mod_expires.c> ExpiresActive on #打开该功能的开关 ExpiresByType image/gif "access plus 1 days" ExpiresByType image/jpeg "access plus 24 hours" ExpiresByType image/png "access plus 24 hours" ExpiresByType text/css "now plus 2 hour" ExpiresByType application/x-javascript "now plus 2 hours" ExpiresByType application/javascript "now plus 2 hours" ExpiresByType application/x-shockwave-flash "now plus 2 hours" ExpiresByType "now plus 0 min" </IfModule>
需要expires module
curl测试，看cache-control:max-age

     45         RewriteEngine on
     46         RewriteCond %{HTTP_HOST} !^111.com$
     47         RewriteRule ^/(.*)$ http://111.com/$1 [R=301,L]
     48     </IfModule>
     49     <IfModule mod_expires.c>
     50         ExpiresActive on
     51         ExpiresByType image/gif "access plus 1 days"
     52         ExpiresByType image/jpeg "access plus 24 hours"
     53         ExpiresByType image/png "access plus 24 hours"
     54         ExpiresByType text/css "now plus 24 hours"
     55         ExpiresByType application/x-javascript "now plus 2 hours"
     56         ExpiresByType application/javascript "now plus 2 hours"
     57         ExpiresByType application/x-shockwave-flash "now plus 2 hours"
     58         ExpiresDefault "now plus 0 min"
     59     </IfModule>
     60     ErrorLog "logs/111.com-error_log"

将expires模块打开

[root@localhost 111.com]# /usr/local/apache2.4/bin/apachectl -M | grep expires
 expires_module (shared)
[root@localhost 111.com]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@localhost 111.com]# /usr/local/apache2.4/bin/apachectl graceful

[root@localhost 111.com]# curl -x 127.0.0.1:80 111.com/1111.png -I
