DNT Aware Page Cache

This module provides a page cache for anonymous users that behaves identically to the Drupal Core Internal Page Cache Module with one exception: it stores cached versions for users with the Do Not Track (DNT) header set separately from those without.

This is important for ensuring conformance of data gathering scripts in jurisdictions and for clients who wish to respect Do Not Track.

The module should not be active at the same time as the normal Drupal Core Internal Page Cache, and implements hook_requirements() in order to complain when the core cache is active.
