Q:

CakePHP cannot modify header?

I am using CakePHP 1.3 and it keeps telling me the following.

Cannot modify header information

This ONLY happens when I include the Auth component.
  var $components = array('Auth');

Am I doing something wrong, a bug, or what?

A:

Headers have to be the first part of a web page that you send. Make sure that you haven't outputted any other information before you try sending any kind of header.
