Why the error 404 happens when I access *.mp4 file by HTTP?

Question

I have some shared folder over HTTP. Lets say: http://myserver/files

And there are some filed like png, avi, jpg, mp4 and etc.

I can easily access *.png or *

Answer 1

So I found the solution.

I just added correct MIME type to my website.

Extension: mp4

MIME type: video/mpeg

And now it works fine.
