response body. Similar to the individual Info method, the response for a successful AggregateInfo

method execution is a 200 code.

The following is a sample checkpoint manifest stream. All object names must be URL-encoded so

you must use percent encoding to escape special characters in named objects, including space. All

line terminators must be CRLF:

The checkpoint manifest should be stored in the local cluster and its name or UUID used to issue

the AggregateInfo request. The AggregateInfo method supports named and unnamed objects

for both the manifests and streams stored in the manifest. It supports authentication only for the

manifest stream itself, and checkpoint streams in the manifests that are protected for HEAD are

returned as 401s in the AggregateInfo response body.

Any additional query arguments and headers included with the AggregateInfo method apply to the

GET request issued for the checkpoint manifest only and are not included in the individual Info

requests for each name or UUID in the manifest. If the checkpoint manifest is stored in an unnamed

anchor stream, the AggregateInfo method must be called with alias=yes in its queryArg

dictionary.

AggregateInfo uses Aggregate-Stream-Count as its trailer header.

Expect: Content-MD5 and Range headers, as well as any integrity seal query arguments, are

not supported for the AggregateInfo method.

1.2.3.1. Aggregate Info Response

For each line of the checkpoint manifest, the SCSP Proxy uses chunked encoding to send in the

AggregateInfo response body either a parse error for the line or the line's name or UUID followed by

the DX Storage's verbatim response for the Info query for it. A CRLF line-end sequence separates

the uuid line from the Info response. For example, for a manifest that included two UUIDs, both of

which the SDK was able to Info successfully, the following representative response body would be

returned:

Response for stream uuid = 64f9e40bfcb7046d79cc02c5876c1904
