Yup, that's basically what I do. Anyway the problem was that I did something stupid (as always). I do a redirect at the end of the page if the headers are not sent, because I have a lot of tests (if:s) and for each fail and some of the successful ones I want to redirect the user back to the main-page. So I trusted that if I wrote some HTML, the headers would've been sent and no redirect performed. No need to say that that was a bad thing to trust. Now I do an exit after emitting HTML instead.
