Retrieve the current page from the cache.

Note: we do not serve cached pages when status messages are waiting (from a redirected form submission which was completed).


$status_only: When set to TRUE, retrieve the status of the page cache only (whether it was started in this request or not).

In Drupal 7 and onwards, this function is renamed drupal_page_get_cache().
