apache 有点旧，但是我对它的印象还不错，就是操作上比nginx多做了一丢丢。
有个应用，
1. 前提： 先看看 apache 的设置，确保 enable 了 headers, expires
$ a2enmod headers $ a2enmod expires $ service apache2 restart
2. 在对应的配置文件中，加上内容：
<VirtualHost *:80>
....
<Directory "/opt/your_app">
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
# add this line:
ExpiresDefault "access plus 30 days"
</Directory>
</VirtualHost>
或者，在对应的 virtualhost 目录下的 .htaccess中：（完整代码见：http://stackoverflow.com/questions/12497601/force-browser-cache-css-and-js-files-gzipped-with-apache-php
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
</ifModule>
以及下面的部分：
<ifModule mod_headers.c>
<filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
<filesMatch "\\.(css)$">
Header set Cache-Control "max-age=604800, public"
</filesMatch>
<filesMatch "\\.(js)$">
Header set Cache-Control "max-age=216000, private"
</filesMatch>
<filesMatch "\\.(xml|txt)$">
Header set Cache-Control "max-age=216000, public, must-revalidate"
</filesMatch>
<filesMatch "\\.(html|htm|php)$">
Header set Cache-Control "max-age=1, private, must-revalidate"
</filesMatch>
</ifModule>
