SYMPTOMS

The Wininet.dll file does not handle redirection from an HTTPS URL to an HTTP URL in Microsoft Windows XP with Service Pack 2.

CAUSE

This problem occurs because of a security check in the Wininet.dll file. The security check prevents the Wininet.dll file from handling the redirection if the referrer header is not present in the request header.
