That's a bit misleading. The HTTP response headers are sent a soon

setcookie() doesn't count as output, so you can set all the headers
and cookies you want).
They're sent to Apache, but that doesn't mean anything is necessarily sent to the client, right? I guess I should have pointed out that this depends on a few things, such as whether the response is sent with:
Transfer-Encoding: chunked
or
Content-Length: ...
Common sense tells me that Apache can't provide a reliable Content-Length header until my script completes. :-)
That's true... it can't... and doesn't... at least not all the time...
