My browser sends the following request to the server:

And the server will send me a file with this http (http: http: // http: // http:

As you may have noticed ( Last-Modified: Fri, 29 May 2015 14:22:44 GMT ), the file has not been modified since the last request.
So I don’t understand why the answer is not status 304: not changed.
I would really like to know why caching these files (and some others) does not work as I expect.
