When a web server accesses files, the server must properly identify the files as Flash content to display them. If the MIME type is missing or not properly delivered by the server, the browser can show error messages or a blank window with a puzzle-piece icon.

If your server is not properly configured, you (or your server’s administrator) must add the SWF file MIME types to the server’s configuration files and associate the following MIME types with the SWF file extensions:

• MIME type application/x-shockwave-flash has the .swf file extension.

• MIME type application/futuresplash has the .spl file extension.

If you are administering a server, consult your server software documentation for instructions on adding or configuring MIME types. If you are not administering a server, contact your Internet service provider, web master, or server administrator to add the MIME type information.

If your site is on a MAC OS server, you must also set the following parameters: Action: Binary; Type: SWFL; and Creator: SWF2.
