INTRODUCTION
You may experience unexpected behavior when you send a request for a resource that has the .map file name extension to a server that is running Internet Information Services (IIS). This issue may occur because of the algorithm that IIS uses to determine whether the resource contains a valid server-side image map. In the following versions of IIS, the .map file name extension is reserved for server-side image map processing:
 * IIS 6.0
 * IIS 5.1
 * IIS 5.0

Do not use the .map file name extension for other purposes.



MORE INFORMATION
When you send a request for a resource that has a .map file name extension to IIS, you may experience one or more of the following symptoms:
 * The XML source or the code source of the resource appears in the browser window.
 * A list of the files appears in the browser window. These files are in the folder in which the .map file is located.

Note You may experience symptoms that are not listed.
