Configure MIME types
Customers may create custom MIME types on a Linux shared hosting account by adding the AddType directive to an .htaccess file. Customers can create custom MIME types on a Windows shared hosting account by modifying the web.config file.
Linux
The .htaccess file should reside in the same directory as the designated files. The .htaccess entry has the following syntax:
AddType mime-type ext
Using the .wmv file extension as an example, the .htaccess entry would be the following:
AddType video/x-ms-wmv wmv
Windows
The web.config file should be located in the root directory of a 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>
