calculateChunkedContentLength

public static long calculateChunkedContentLength(long originalLength,
                                                 long chunkSize)

Calculates the expanded payload size of our data when it is chunked

Parameters:

originalLength - The true size of the data payload to be uploaded

chunkSize - The size of each chunk we intend to send; each chunk will be prefixed with signed header data, expanding the overall size by a determinable amount

Returns:

The overall payload size to use as content-length on a chunked upload
