Note Submitter: DanRichter.at.programmer.dot.net ---- Make sure none of your library files begin or end with a blank line, at least if you ever want to use cookies or other headers. Otherwise, you will get errors like this: Warning: Cannot send session cache limiter - headers already sent That's because even though you may consider the include file just a library, Apache considers it a source of HTML, so that blank line will be the first line of the document. Then when you get around to setting the cookie or header, Apache can't do it because it's already started sending the body.
