I’d say never.
If I wanted something to be set via the various methods, I’d code for each of them to remind myself that I’d done it that way – otherwise you might end up with things being overwritten without realising.
Shouldn’t it work like this:
$_GET = non destructive actions (sorting, recording actions, queries)
$_POST = destructive actions (deleting, updating)
$_COOKIE = trivial settings (stylesheet preferences etc)
$_SESSION = non trivial settings (username, logged in?, access levels)
