view() is run just before the content of the view is rendered, so way after all headers have been output. The usual use of view() is to set up data for the single page or block view.

In a page or package controller on_start() ( or for a block, on_page_view() ), is run before any headers are output, so can be used to add css or script to headers, set up event handlers (and more).
