问题描述
我正在使用jwplayer以html5模式播放视频.视频为mp4格式.
I'm using jwplayer to play videos in html5 mode.Videos are in mp4 format.
我在网络"标签中看到的是一堆状态为206(部分下载)的网络请求.因此，我的理解是->视频仅以部分块的形式进行流传输，每个块1-2 Mb.
What I'm seeing in the network tab are bunch of network requests with 206 status (partial download). So my understanding is -> video is just being streamed in partial chunks, 1-2 Mb each.
但是这些块可以缓存在浏览器中吗?目前，我看到视频每次都在重新流式传输...
But can those chunks be cached in the browser?Currently I'm seeing video just being re-streamed every time...
推荐答案
参考此答案:是，206响应是可缓存的.这也在 RFC 7233第4.1节中明确声明:
With reference to this answer: Yes, 206 responses are cacheable. This is also explicitly stated in RFC 7233, section 4.1:
这当然并不意味着浏览器 do 会缓存它们.但是他们当然可以.
This does not mean that browser do cache those, of course. But they certainly can.
