+=head1 CAVEATS
+
+Sessions have to be created before the first write to be saved. For example:
+
+	sub action : Local {
+		my ( $self, $c ) = @_;
+		$c->res->write("foo");
+		$c->session( ... );
+		...
+	}
+
+Will cause a session ID to not be set, because by the time a session is
+actually created the headers have already been sent to the client.
