Common response headers

In addition to standard HTTP headers, ColdStack uses additional headers that may be present in responses.

Additional headings are described in the table below, as well as standard headings for which additional explanation is required.

Heading	Description
ETag	MD5 hash of the object, if the object is loaded as a single file. If the object is loaded using a compound load , then for the calculation ETagit is necessary to obtain the MD5 hash from the sum of the MD5 hashes of the loaded parts (let's call it MD5_sum) and attach the number of parts ( N): to the resulting string "MD5_sum-N". Does not include object metadata.
x-amz-request-id	Unique identifier for the request. It may be needed when contacting ColdStack support in case of problems.
