FW: Public call for prior art on Do Not Track Headers

Three quick references to prior art for "preference expression methods (privacy or otherwise) that were available before February 2007".

1) WAP Forum, Wireless Application Protocol, Wireless Application Environment Specification, Version 30-Apr-1998, WAEspec-30-apr-98.PDF URL: http://technical.openmobilealliance.org/tech/affiliates/LicenseAgreement.asp?DocName=/wap/technical%5B1%5D.zip 
Included the ability to disclose user agent capabilities and user preferences through a URI-referenced document (the User Agent Profile or UAProf). UAProfs were typically unique to WAP phone models and typically referenced the same URI (hosted by the OEM), although the URI reference approach was defined to allow user agents to be deployed with customizable UAProfs which could differ from the default browser UAProf per arbitrary considerations, e.g. user preferences in general including privacy.

2) WAP Forum, Wireless Application Group, User Agent Profile Specification, Version 10-Nov-1999, SPEC-UAProf-19991110.pdf
URI: http://technical.openmobilealliance.org/tech/affiliates/LicenseAgreement.asp?DocName=/wap/technical_1_2_20011112%5B1%5D.zip
Further clarified the privacy-related intent of the UAProf technology with the statement "Finally, it is expected that this specification will be used to enhance content personalization based on user preferences, and other factors, as enabled by the Platform for Privacy Preferences Project (P3P) [P3P]." on Page 9 (Section 4).

3) WAP Forum, HTTP State Management Specification, 13-DEC-2000, WAP-223-HTTPS-20001213-a, WAP-223-HTTPSM-20001213-a.pdf
URI: http://technical.openmobilealliance.org/tech/affiliates/LicenseAgreement.asp?DocName=/wap/technical_wap2_0-20021106.zip
Introduced the "X-Wap-Proxy-Cookie" header through which user agents could disable the storage of cookies in the WAP proxy.

Thanks,
Bryan Sullivan

Subject: Public call for prior art on Do Not Track Headers

http://www.w3.org/2012/dnt-pag/cfpa

The W3C hereby issues a call for prior art on US patent 8,156,206 [1]
that may apply to the Tracking Preference Expression (DNT) 
Specification[2]. An outside party (who is contributing postings to the 
Working Group mailing list) has been alerting participants in the 
Working Group about US Patent Nr. 8,156,206. 

The PAG seeks information about preference expression methods (privacy 
or otherwise) that were available before February 2007, and provide 
evidence of prior art that would help to resolve the patent issue at 
hand.

People who wish to provide feedback should refer to the call[3] for more 
information or write back to public-dnt-pag@w3.org

Please distribute this call for prior art as widely as possible.
