Browser File Handling 
Specifies whether additional security headers are added to documents served to web browsers. These headers specify that a browser should show a download prompt for certain types of files (for example, .html) and to use the server's specified MIME type for other types of files.

• Permissive Specifies no headers are added, which provides a more compatible user experience.
• Strict Adds headers that force the browser to download certain types of files. The forced download improves security for the server by disallowing the automatic execution of Web content that contributors upload.
