apache_note — Get and set apache request notes
Description
$note_name
[, string $note_value = ""
] ) : stringThis 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.
Return Values
If called with one argument, it returns the current value of note
note_name. If called with two arguments, 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.
Examples

my $r = Apache->request()->main();
# Get passed data
my $name = $r->notes('name');
