Interface BlobDownloadHeaders

Indicates that the service supports requests for partial blob content.

The number of committed blocks present in the blob. This header is returned only for append blobs.

If the blob has a MD5 hash, and if request contains range header (Range or x-ms-range), this response header is returned with the value of the whole blob's MD5 value. This value may or may not be equal to the value returned in Content-MD5 header, with the latter calculated from the requested range

The current sequence number for a page blob. This header is not returned for block blobs or append blobs

The blob's type. Possible values include: 'BlockBlob', 'PageBlob', 'AppendBlob'

This header is returned if it was previously specified for the blob.

If a client request id header is sent in the request, this header will be present in the response with the same value.

If the request is to read a specified range and the x-ms-range-get-content-crc64 is set to true, then the request returns a crc64 for the range, as long as the range size is less than or equal to 4 MB. If both x-ms-range-get-content-crc64 & x-ms-range-get-content-md5 is specified in the same request, it will fail with 400(Bad Request)

This header returns the value that was specified for the 'x-ms-blob-content-disposition' header. The Content-Disposition response header field conveys additional information about how to process the response payload, and also can be used to attach additional metadata. For example, if set to attachment, it indicates that the user-agent should not display the response, but instead show a Save As dialog with a filename other than the blob name specified.

This header returns the value that was specified for the Content-Encoding request header

This header returns the value that was specified for the Content-Language request header.

The number of bytes present in the response body.

If the blob has an MD5 hash and this operation is to read the full blob, this response header is returned so that the client can check for message content integrity.

Indicates the range of bytes returned in the event that the client requested a subset of the blob by setting the 'Range' request header.

The media type of the body of the response. For Download Blob this is 'application/octet-stream'

Conclusion time of the last attempted Copy Blob operation where this blob was the destination blob. This value can specify the time of a completed, aborted, or failed copy attempt. This header does not appear if a copy is pending, if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List.

String identifier for this copy operation. Use with Get Blob Properties to check the status of this copy operation, or pass to Abort Copy Blob to abort a pending copy.

Contains the number of bytes copied and the total bytes in the source in the last attempted Copy Blob operation where this blob was the destination blob. Can show between 0 and Content-Length bytes copied. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List

URL up to 2 KB in length that specifies the source blob or file used in the last attempted Copy Blob operation where this blob was the destination blob. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List.

State of the copy operation identified by x-ms-copy-id. Possible values include: 'pending', 'success', 'aborted', 'failed'

Only appears when x-ms-copy-status is failed or pending. Describes the cause of the last fatal or non-fatal copy operation failure. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List

UTC date/time value generated by the service that indicates the time at which the response was initiated

The SHA-256 hash of the encryption key used to encrypt the blob. This header is only returned when the blob was encrypted with a customer-provided key.

The ETag contains a value that you can use to perform operations conditionally. If the request version is 2011-08-18 or newer, the ETag value will be in quotes.

The value of this header is set to true if the blob data and application metadata are completely encrypted using the specified algorithm. Otherwise, the value is set to false (when the blob is unencrypted, or if only parts of the blob/application metadata are encrypted).

Returns the date and time the container was last modified. Any operation that modifies the blob, including an update of the blob's metadata or properties, changes the last-modified time of the blob.

When a blob is leased, specifies whether the lease is of infinite or fixed duration. Possible values include: 'infinite', 'fixed'

Lease state of the blob. Possible values include: 'available', 'leased', 'expired', 'breaking', 'broken'

The current lease status of the blob. Possible values include: 'locked', 'unlocked'

This header uniquely identifies the request that was made and can be used for troubleshooting the request.

Indicates the version of the Blob service used to execute the request. This header is returned for requests made against version 2009-09-19 and above.
