2.0 P3P ClickStream Data Element
The ClickStream data element is the primary method P3P deals with defining the data collected in the web log.

The clickstream element is expected to apply to practically all Web sites. It represents the combination of information typically found in Web server access logs: the IP address or hostname of the user's computer, the URI of the resource requested, the time the request was made, the HTTP method used in the request, the size of the response, and the HTTP status code in the response. Web sites that collect standard server access logs as well as sites which do URI path analysis can use this data element to describe how that data will be used. Web sites that collect only some of the data elements listed for the clickstream element MAY choose to list those specific elements rather than the entire dynamic.clickstream element. This allows sites with more limited data-collection practices to accurately present those practices to their visitors.

2.1 P3P HTTP Data Element
The HTTP data element should be combined with the clickstream data element to give a full picture of the items collected in the web log.

The http element contains additional information contained in the HTTP protocol (Last URI Requested by the User and User Agent Information). Sites MAY use the dynamic.http field as a shorthand to cover all the elements in the httpinfo structure if they wish, or they MAY reference the specific elements in the httpinfo structure.
