23 * CommandHandler for the DELE command. Handler logic:
24 * <ol>
25 * <li>If the user has not logged in, then reply with 530</li>
26 * <li>If the required pathname parameter is missing, then reply with 501</li>
27 * <li>If the pathname parameter does not specify an existing file, or if the delete fails, then reply with 550</li>
28 * <li>Otherwise, reply with 250</li>
29 * </ol>
30 * The supplied pathname may be absolute or relative to the current directory.
