Default Case of Image Map Is Case Sensitive in IIS

Last reviewed: April 22, 1997
Article ID: Q151621

The information in this article applies to:
  • Microsoft Internet Information Server version 1.0
  • Microsoft Internet Explorer version 2.0

SYMPTOMS

When you click an image map using Internet Explorer 2.0, the browser will get stuck in an infinite loop trying to go to the link on the image map. You will see the icon on the title bar flash and the contents of the status bar will flash as Internet Explorer tries to reload the page. You can break out of the loop using the Stop button on the browser.

CAUSE

Given the following image map:

   DEFAULT http://server/file.htm
   rect (0,1) (170,53) http://server/file1.htm
   rect (264,26) (349,53) http://server/file2.htm
   rect (187,23) (264,53) http://server/file3.htm

If you click an area not defined by one of the shapes, the DEFAULT case should be returned by the server. Internet Information Server (IIS) returns a Location: header that is blank. This causes Internet Explorer to loop continuously.

WORKAROUND

Change the word DEFAULT in the map file to all lower case.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Internet Information Server version 1.0 and Microsoft Internet Explorer version 2.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
