Matthieu,

The blocks must be sent sequentially in order, from the upstream partner to the downstream partner. The first block contains the staging header and the first part of the staging file data. A later block must not be processed unless the previous block has been downloaded successfully, as specified in Section 3.3.4.4.8.
This is well documented in Sections 3.3.4.4.8, and 3.3.4.4.6.1. Section 2.2.3.10 also provides details that the file data must be processed in chunks of 64KB blocks.

Dear doc help,

For a file that don't fit in one chunk (>65535), is the downstream partner (the one that is sending it) required to send the chunks in order or not ?

Matthieu.
