1515: At the end of a succesful request, the urlName string contains the

1517: (e.g., be redirected elsewhere), it is advised that the function
1518: caller verifies the value of the urlName variable at the end of

1520:
1521: Inputs:
1522: - docid Document identifier for the set of objects being

1524: - fileName A pointer to the local file to upload
1525: - urlName The URL to be uploaded (MAX_URL_LENGTH chars length)
