June Change Proposal: Protocol Information and Contextual Advertising

I would propose adding the following definition of protocol information:

> Protocol information includes:
> any information that a user agent necessarily shares with a web server when it communicates with the web server (e.g. IP address and User-Agent), and
> the URL of the top-level page, communicated via a Referer header or other means, unless the URL contains information that is not unlinkable (e.g. a username or user ID).
> 
> 
> Protocol information does not include:
> any information that a web server could cause to not be sent but still communicate with the user agent (e.g. a cookie or a Request-URI parameter generated by the user agent), except the URL of the top-level page, and
> any data added by a network intermediary that the operator of a web server has actual knowledge of (e.g. a unique device identifier HTTP header).
> 
> 
> 


And allowing short-term retention and use for any purpose:
> A third party may receive and use protocol information for any purpose, subject to a two-week retention period.
 
Including contextual advertising:
> Under the general rule on protocol information a third party may temporarily use a top-level page URL for the purpose of contextually personalizing content.
