Daniel (19 October 2004)

- Alexander Krasnostavsky made it possible to make FTP 3rd party transfers

  with both source and destination being the same host. It can be useful if

  you want to move a file on a server or similar.

- Guillaume Arluison added CURLINFO_NUM_CONNECTS to allow an app to figure

  out how many new connects a previous transfer required.

  CURLcode status = CURLE_OK;

  struct SessionHandle *data = conn->data;

  struct connectdata *sec_conn = NULL;   /* secondary connection */

  bool reuse_fresh_tmp = data->set.reuse_fresh;

  /* update data with source host options */

  char *url = aprintf( "%s://%s/", conn->protostr, data->set.source_host);

  data->set.ftpport = data->set.source_port;

  data->set.userpwd = data->set.source_userpwd;

  /* if both remote hosts are the same host - create new connection */

  if (strequal(conn->host.dispname, data->set.source_host))

    /* NOTE: this is restored back to the original value after the connect is

       done */

    data->set.reuse_fresh = TRUE;

  /* secondary connection */

  status = Curl_connect_host(data, &sec_conn);

  if(CURLE_OK == status) {

    sec_conn->sec_conn = NULL;  /* important if re-using existing connection

                                   to prevent loop */

    sec_conn->data = data;

    conn->sec_conn = sec_conn;

  }

  data->set.reuse_fresh = reuse_fresh_tmp;

  return status;
