2803:
2804: In the incremental mode, each time a package arrives, it will be
2805: stored in the temporary file. In addition, if an
2806: incremental_callback function is defined, this function will be
2807: called and handled a copy of the newly received data package.

2811: functions.
2812:
2813: When the function is called with the SYNC mode, the function will

2815: The ASYNC mode will immediately return after setting up the

2819: At the end of a succesful request, the urlName string contains the
