When your files are accessed from a web server, the server must properly identify them as Flash Player files in order to display them. If the MIME type is missing or not properly delivered by the server, the browser might display error messages or a blank window with a puzzle piece icon.
To ensure that visitors can see your movies, you (or your server's administrator) must add the Flash Player MIME types to the server's configuration files and associate these MIME types with the Flash Player file extensions. The relevant MIME types and suffixes are:
| MIME type | Suffix |
|---|---|
application/x-shockwave-flash |
.swf |
application/futuresplash |
.spl |
If you are administering your own server, consult your server software documentation for instructions on adding or configuring MIME types. If you are not administering your own server, contact your Internet service provider, webmaster, or IT department and ask them to add the MIME type information.
If your site is on a Macintosh server, you must also set the following parameters: Action: Binary; Type: SWFL; and Creator: SWF2.
