note 77918 deleted from function.session-start by peehaa

Note Submitter: ehassler at synapsestudios dot com ---- At work we had an odd warning, "Cannot send session cache limiter - headers already sent". In the following: header('meta:1'); session_start(); the first header went across fine, but the session_start died with the warning. What was happening was that the session contained an object which fired __autoload() when it was unserialized. The __autoload() then included the file with the class definition, but that file also output non-header text. This caused session_start() to be unable to add the session_id to the headers. This was difficult to find because we weren't able to see the text that was output from the file that was __autoload()ed, only the warning.
