2467:
2468: In the incremental mode, each time a package arrives, it will be

2470: incremental_callback function is defined, this function will be
2471: called and handled a copy of the newly received data package.

2476:

2479: The ASYNC mode will immediately return after setting up the

2482: Notes:
2483: At the end of a succesful request, the urlName string contains the
2484: name of the actually retrieved URL. As a URL can change over the time,

2492: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
