function page_get_cache in Drupal 4

Same name and namespace in other branches

1. 5 includes/bootstrap.inc \page_get_cache()
2. 6 includes/bootstrap.inc \page_get_cache()

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). Because the output handler is not activated, the resulting page will not get cached either.
