I think that video is cached because second request wasn't sent to server

https://github.com/misikdmitriy/firefox-cache - here is repository

1. clone repository to your local machine;
2. open command prompt in project root folder and enter "npm install";
3. then enter "npm start";
4. open page "localhost:3000" in your browser. you should see the video;
5. copy "video2.mp4" from folder "original" in project root folder;
6. remove "video.mp4" in root folder;
7. rename "video2.mp4" into "video.mp4";

You see old video. What is the reason? Is this cache?

I guess we clone the old MediaCache here
http://searchfox.org/mozilla-central/source/dom/html/HTMLMediaElement.cpp#2446
because the new url is the same as old url!?
