PageSpeed中解决“使用浏览器缓存”的方法

apache环境，在http.conf中新增：

<IfModule mod_expires.c>
ExpiresActive On
<FilesMatch "\.(gif|jpg|png|js|css)$">
ExpiresDefault "access plus 7 days"
</FilesMatch>
</IfModule>

　　

或：

ExpiresActive On
ExpiresByType image/gif "access plus 7 day"
ExpiresByType image/jpg "access plus 7 day"
ExpiresByType image/jpeg "access plus 7 day"
ExpiresByType image/x-icon "access plus 7 day"
ExpiresByType image/bmp "access plus 7 day"
ExpiresByType image/png "access plus 7 day"
ExpiresByType text/html "access plus 7 day"
ExpiresByType text/css "access plus 7 day"
ExpiresByType text/txt "access plus 7 day"
ExpiresByType text/js "access plus 7 day"
ExpiresByType application/x-javascript "access plus 7 day"
ExpiresByType application/x-shockwave-flash "access plus 7 day"

保存后重启web服务即可。
