是否可以通过HTML5 / jQuery从视频获取HTTP标头？

Question

We're playing around with jPlayer, and we want to be able to inspect the http headers (even from a remote user so wireshark is not possible) from the video file as it is getting parsed -- you can assume we're just going to use the video tag. You can get headers from an AJAX call in jQuery, so I was wondering if it's possible to get the headers from any resource, be it an image, video, css file, etc?

Answer 1

within the browser you cannot today, it would need to be via an external tool.

I would suggest piling on this request - https://www.w3.org/Bugs/Public/show_bug.cgi?id=14310 - with your use-case
