Video file access error in IIS virtual directory: HTTP error 404.3-not Found The page you requested could not be supplied due to an extended configuration issue. If the page is a script, add a handler. If you should download the file, add a MIME map.

A MIME type is a type of file that sets an extension that is opened by an application, and the browser automatically opens with the specified application when the extension file is accessed. Many are used to specify some client-customized file names, as well as some ways to open media files.

I was in the configuration of the WIN7 server, I encountered such a problem, I in the ASP server virtual directory "Asptest" decentralized a video file "Video.mp4", the results of my browser directly access to Http://localhost/asptest/video.mp4, it appears

HTTP error 404.3-not found the page you requested is not available due to an extended configuration issue. If the page is a script, add a handler. If you should download the file, add a MIME map.

The solution is as follows

1. Open IIS Manager (run inetmgr)

2. Click on the root node

3. On the right, under IIS, find the MIME type double-click to open

4. Add the file extension to the right: "mp4", MIME type (M): "Video/mp4"

This will add a good mime-type mapping.
