Create custom MIME types

You can create custom MIME types on a Windows shared hosting account by modifying the web.config file.

The web.config file should be located in the root directory of your Web site. Using MP4 and MPV as examples, adding MIME types with IIS 7 looks like this:

<configuration><system.webServer><staticContent><mimeMap fileExtension=".mp4" mimeType="video/mp4" /><mimeMap fileExtension=".m4v" mimeType="video/m4v" /></staticContent></system.webServer></configuration>
