35 * Test case for below scenario:
36 *   - Connect to an FTP server using CONNECT_ONLY option
37 *   - transfer some files with re-using the connection (omitted in test case)
38 *   - Disconnect from FTP server with sending QUIT command
39 *
40 * The test case originated for verifying CONNECT_ONLY option shall not
41 * block after protocol connect is done, but it returns the message
42 * with function curl_multi_info_read().
