2801:
2802: In the incremental mode, each time a package arrives, it will be

2804: incremental_callback function is defined, this function will be
2805: called and handled a copy of the newly received data package.

2810:

2813: The ASYNC mode will immediately return after setting up the

2817: At the end of a succesful request, the urlName string contains the
