For users to view your Flash content on the web, the web server must be properly configured to recognize SWF files.

Your server may already be configured properly. To test server configuration, see TechNote 4151 on the Adobe Flash Support Center at www.adobe.com/go/tn_4151.

Configuring a server establishes the appropriate Multipart Internet Mail Extension (MIME) types so that the server can identify files with the .swf extension as Flash files.

A browser that receives the correct MIME type can load the appropriate plug‑in, control, or helper application to process and properly display the incoming data. If the MIME type is missing or not properly delivered by the server, the browser might display an error message or a blank window with a puzzle piece icon.

• If your site is established through an Internet service provider (ISP), ask the ISP to add this MIME type to the server: application/x-shockwave-flash with the .swf extension.

• If you are administering your own server, see your web server documentation for instructions on adding or configuring MIME types.

• Corporate and enterprise system administrators can configure Flash to restrict Flash Player access to resources in the local file system. Create a security configuration file that limits Flash Player functionality on the local system.

The security configuration file is a text file placed in the same folder as the Flash Player installer. The Flash Player installer reads the configuration file during installation and follows its security directives. Flash Player uses the System object to expose the configuration file to ActionScript.

With the configuration file, disable Flash Player access to the camera or microphone, limit the amount of local storage Flash Player can use, control the auto-update feature, and block Flash Player from reading anything from the user’s local hard disk.

For more information about security, see System in ActionScript 2.0 Language Reference.
