How to add MIME types in .htaccess?
AddType is specifying that you are adding a MIME type. The application string is the actual parameter of the MIME you are adding, and the final little bit is the default extension for the MIME type you just added, in my example this is swf for ShockWave File.
AddType application/x-shockwave-flash swf
web hosting account is not configured to server certain mime types with the proper content type. You can change this using .htaccess file.
For example if you need to configure your server to display ASX files:
AddType video/x-ms-asf asf asx
For windows media audio WMA
AddType audio/x-ms-wma .wma
