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

Add a MIME type with extension mp4 in IIS

But please note that you should set the MIME type video/mp4 instead of video/mpeg orelse in IE "Save Target As.." shows different format, and it also affects the default video player open by browser.

video/mpeg

File name: test.mpeg

Save as type: Movie Clip

video/mp4

File name: test.mp4

Save as type: MP4 Video
