Apache 配置静态缓存

我们可以给一个网站配置静态缓存，缓存一些图片或文字之类的，这样用户再次访问我们网站的时候就不用再加载图片或文字了，因为已经缓存在客户端了，可以节省我们的带宽，同时提高访问速度，Apache 配置静态缓存通过添加 expires 模块来实现

[root@localhost ~]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
<VirtualHost *:80>
    DocumentRoot "/data/www"
    ServerName www.test.com
    ErrorLog "logs/test.com_error_log"
    CustomLog "logs/test.com_access_log" combined 
<IfModule mod_expires.c>
 ExpiresActive on
 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"
 ExpiresDefault "now plus 0 min"
 </IfModule>
</VirtualHost>

[root@localhost ~]# /usr/local/apache2/bin/apachectl -t
