will return the contents of the original manifest as it was sent by the client.
|

The main purpose for both calls is solely debugging.

When the manifest object is uploaded you are more or less guaranteed that
|

every segment in the manifest exists and matched the specifications.

However, there is nothing that prevents the user from breaking the

SLO download by deleting/replacing a segment referenced in the manifest. It is

left to the user to use caution in handling the segments.
|

A GET request to a manifest object with the query parameter::
|
||||
|
||||
?part-number=<n>
|
||||
|
||||
will return the contents of the ``nth`` segment. Segments are indexed from 1,
|
||||
so ``n`` must be an integer between 1 and the total number of segments in the
|
||||
manifest. The response status will be ``206 Partial Content`` and its headers
|
||||
will include: an ``X-Parts-Count`` header equal to the total number of
|
||||
segments; a ``Content-Length`` header equal to the length of the specified
|
||||
segment; a ``Content-Range`` header describing the byte range of the specified
|
||||
part within the SLO. A HEAD request with a ``part-number`` parameter will also
|
||||
return a response with status ``206 Partial Content`` and the same headers.
