Default Case of Image Map Is Case Sensitive in IISLast reviewed: April 22, 1997Article ID: Q151621 |
The information in this article applies to:
SYMPTOMSWhen 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.
CAUSEGiven 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.htmIf 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.
WORKAROUNDChange the word DEFAULT in the map file to all lower case.
STATUSMicrosoft 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.
