24 * CommandHandler for the RNFR command. Handler logic:
25 * <ol>
26 * <li>If the user has not logged in, then reply with 530</li>
27 * <li>If the required FROM pathname parameter is missing, then reply with 501</li>
28 * <li>If the FROM pathname parameter does not specify a valid file, then reply with 550</li>
29 * <li>Otherwise, reply with 350 and store the FROM path in the session</li>
30 * </ol>
31 * The supplied pathname may be absolute or relative to the current directory.
