ASP <%= Request.Form() %> Returns Blank

• Microsoft Internet Information Server version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

ASP <%= Request.Form() %> returns blank if the browser sends the duplicate "Content-Type : application/x-www-form-urlencoded" header field to an Internet Information Server computer. The correct content is returned if the page is refreshed in the browser. This problem may occur if the ASP page referenced in the Form tag in a page is in a different virtual directory with a different authentication method.

CAUSE

Internet Information Server (IIS) failed to properly handle the redundant Content-Type header field.

RESOLUTION
