Is it possible to set different cache-control headers for CDN and browser? Currently, I am using
header("Cache-Control: max-age=3600, public");
由于我是公开的,我认为,浏览器和CDN都在打上1小时的网页。 我先从CDN上台,以便CDN服务器从网络主机上检索网页。
我想客座时间为10分钟,CDN需要一小时。 这是可能的。
如果无法做到这一点,我就想让浏览者把内容放在一边,而裁谈会则每小时一次。
它是可能的,但取决于具体的裁谈会。 总的来说,国家计算机网络将以同样的方式解释Cache-Control头盔。 CNN拥有控制海滩的专有机制。 例如,Akamai将读成一个专有的吉大港游轮头(X-Akamai-something),高于标准骑士。
It is possible to have different cache control setting for Browser and CDN. So there are two types of cache control setting:
1). Browser to Edge server cache control setting: this is usually done at Origin server and CDN usually respects that setting.
2). Edge server to Origin cache control setting: this is usually done at CDN layer. In addition, configuration can also be added at CDN layer to override that cache control setting from Origin server as in 1).
因此,简言之,你对Browser和CDN可以有不同的切身控制环境,你也可以选择不在Browser,而只选择在CDN层的海滩。
