OK, you have to respond with a -1. But once you send ANY output, you
can't use a header() call.
header() must be called before the headers are sent to the browser. And
any output - even white space - will cause the headers to be sent. So
you can either send a response or do the redirect. But the HTTP
protocol (not PHP) won't let you do both.
