apache_note() does not work on requests to a symlink, only on actual files. Eg. if index.php is symlinked to login.php, then any apache_note() in login.php will not be available to other apache modules such as logging.

apache_note — Get and set apache request notes
Description
This function is a wrapper for Apache's table_get and
table_set. It edits the table of notes that exists
during a request. The table's purpose is to allow Apache modules to
communicate.
The main use for apache_note() is to pass information from one module to another within the same request.
Parameters
-
note_name -
The name of the note.
-
note_value -
The value of the note.
Return Values
If note_value is omitted or null, it returns the current value of note
note_name. Otherwise, it
sets the value of note note_name to
note_value and returns the previous value of
note note_name.
If the note cannot be retrieved, false is returned.
