设置了Cache-Control:max-age=0, 重启浏览器输入url访问还是会从缓存中读资源?
rt 为什么会是200(from cache)
回复内容:
rt 为什么会是200(from cache)
200(from cache)是不像服务器发送请求,直接读取的缓存
304 是向服务器发送请求,服务器认为本地有缓存,就读取缓存
200(from cache)是哪个资源请求?
带有Cache-Control:max-age=0 header头的又是你的哪个资源请求?
同一个资源请求,带有Cache-Control:max-age=0 header头,一般不会返回200(from cache),
返回的是304 Not Modified 或者 200 OK;
