A page view field is included in an HTTP request that contains a requested URL and indicates the URL for the web page or other document from which the requested URL was obtained (either directly or indirectly). Certain processes may be used to help insure that the URL included in the page view field is the URL of the web page or other document that caused the information to be requested (i.e., the web page or other document from which the requested URL was obtained, either directly or indirectly). The page view field may be used by a proxy or other server to perform processing related to a number of applications. The processing, for instance, may relate to access controls (e.g., parentally controlled accounts) or to accurately tracking frequently requested resources such as web pages.
