If your application outputs something ( like an error message or a
blank line out of the <?php ?> ) you can't modify headers.
Raw HTTP response:
-------------------------------
HTTP/1.1 200 OK
<-- headers begin
Date: Sun, 25 May 2008 23:42:55 GMT
Server: Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5 with Suhosin-Patch
Last-Modified: Fri, 02 May 2008 00:21:54 GMT
ETag: "1cf38-2d-44c345e7b6c80"
Accept-Ranges: bytes
Content-Length: 45
Connection: close
Content-Type: text/html
<-- headers ends
<html><body><h1>It works!</h1></body></html>
<-- data for the response
So if you started to output the data, you can't add headers. So you
better make sure you aren't outputting nothing before trying to send
headers.
Other alternative is to use output buffering.
Keep in mind that sending a redirect header does not stop the
execution of your script, you need to call exit.
All of this and much more can be found in the PHP manual: http://php.net
And if you need to know how cake does the redirect, simply look into
source the code:
