Could you tell me the difference of Expires and Cache-control:max-age?

推荐答案

Expires 在 HTTP / 1.0 规范中定义， Cache-Control 在 HTTP / 1.1 规格。

Expires was defined in the HTTP/1.0 specifications, and Cache-Control in the HTTP/1.1 specifications.

我建议定义两者，以便您同时满足两者的需求 HTTP / 1.0 ，以及较新的。

I would suggest defining both so you cater to both, the older clients that only understand HTTP/1.0, and the newer ones.
