Well, JavaScript is client-side stuff which is of course output. You
cannot have anything that needs to set an http header. Such as Header(),
SetCookie() or session_start().
You can use output buffering to get around this limitation, but it is
somewhat expensive. Your best bet is to modify your logic so anything
that needs to send a header happens before any output at all.
