exactly... I don't want to set this option to an entire site just because
of one little script I'm having trouble setting a header() or
setcookie()... and I wanna use them in the middle of the output...
something like ASP's <% response.flush=true %>, it can be set anywhere u
want...
but of course... the best way is to code right and not to mess with headers
once the output has started... but sometimes I wish I could, u know? It
would really make somethings a lot simpler...
