几天前我在做同样的事情。将此添加到我的.htaccess文件中：
ExpiresActive onExpiresByType image/gif A2592000ExpiresByType image/jpeg A2592000ExpiresByType image/jpg A2592000ExpiresByType image/png A2592000ExpiresByType image/x-icon A2592000ExpiresByType text/css A86400ExpiresByType text/javascript A86400ExpiresByType application/x-shockwave-flash A2592000#<FilesMatch ".(gif¦jpe?g¦png¦ico¦css¦js¦swf)$">Header set Cache-Control "public"</FilesMatch>
现在，当我运行google speed page时，利用浏览器缓存不再是重中之重。
希望这可以帮助。
