我已经构建了一个php处理器来处理所有css和js文件。
处理器获取css/js文件的内容,对其进行处理,然后输出到浏览器。
出于某种原因css和js文件拒绝缓存?
谢谢
下面是一些代码:
function setExpires($expires) {
header('Expires: '.gmdate('D, d M Y H:i:s', time()+$expires).' GMT');
header("Cache-Control: max-age=$expires, public");
header("Connection: close");
}
我正在使用谷歌Chrome开发工具。返回的标题如下:
