Article ID: 313558 - Last Review: April 21, 2006 - Revision: 3.0 Privacy policy error occurs when you access sites through the authenticating proxyThis article was previously published under Q313558 On This PageSYMPTOMS
If you use Internet Explorer to browse to a Web site that contains a full privacy policy as defined by the Platform for Privacy Preferences (P3P) specification, and if your request goes through an HTTP proxy that requires authentication, your request for the privacy policy fails with the following error message:
Could not find a privacy policy for site name.
CAUSE
As section 2.4.3 of the P3P specification states, requests for policy reference files fall into a "safe zone." The P3P specification states that the client should transmit very minimal identifying information about the user. In particular, the specification states:
User agents MAY also wish to refrain from sending user agent information or cookies accepted in a previous session on 'safe zone' requests.
Internet Explorer abides by this recommendation and does not transmit authentication credentials to a server when it performs P3P policy reference requests. However, authenticating proxy servers do not abide by the safe zone recommendation and thus reject the attempt by Internet Explorer to request a policy reference without credentials.
RESOLUTION
There is no known workaround at this time. The suggestion by the World Wide Web Consortium (W3C) to put policies in a well-known location does not apply. A proxy requires verification for any file that is requested from the remote server, regardless of location.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. MORE INFORMATIONSteps to Reproduce BehaviorNOTE: To reproduce this behavior, Internet Explorer must direct requests through a proxy that demands user authentication.
Could not find a privacy policy for http://www.microsoft.com/. To view this site's privacy policy, contact the Web site directly.
