The server will respond with one or more packets (depending on if a segmented response was requested and supported by the server), each starting with a Long, which will be one of the following:

The segmented responses contain a full launcher packet split up into multiple segments. To use them, create a buffer of TotalSize bytes, then copy the data from each segment at the given offset.
Following this header, the segmented responses contain a full launcher packet split up into multiple segments. To use them, create a buffer of TotalSize bytes, then copy the data from each segment at the given offset.
