2731:
2732: In the incremental mode, each time a package arrives, it will be

2735: called and handled a copy of the newly received data package.

2743: The ASYNC mode will immediately return after setting up the

2746: Notes:
2747: At the end of a succesful request, the urlName string contains the
2748: name of the actually retrieved URL. As a URL can change over the time,
2749: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2750: caller verify the value of the urlName variable at the end of
