drupal_page_get_cache

Versions
7: drupal_page_get_cache($check_only = FALSE)

Retrieve the current page from the cache.

Note: we do not serve cached pages to authenticated users, or to anonymous users when $_SESSION is non-empty. $_SESSION may contain status messages from a form submission, the contents of a shopping cart, or other user- specific content that should not be cached and displayed to other users.

Parameters

$check_only (optional) Set to TRUE to only return whether a previous call found a cache entry.

Return value

The cache object, if the page was found in the cache, NULL otherwise.
