我在google map
网站中添加了PHP
。现在,我使用Yslow
检查我的网页,并在add expired headers
中看到:
There are 17 static components without a far-future expiration date.
文件是:

如何为Google地图添加过期日期?!
答案 0 :(得分:0)
您无法更改从Google等其他服务加载的组件的到期日期和缓存设置;您只能真正改善您控制的组件(即从您的服务器)。
在这种情况下,我建议从YSlow测量/等级退一步,从用户的角度看你的应用程序是否足够快。如果不是,可能还有其他最佳做法可以使用您可以实施的Google Maps API。
