-- The HEAD operation retrieves metadata from an object without returning the object itself. This operation is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.

-- | Creates a value of 'HeadObject' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'hoIfMatch' - Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).
--
-- * 'hoVersionId' - VersionId used to reference a specific version of the object.
--
-- * 'hoSSECustomerAlgorithm' - Specifies the algorithm to use to when encrypting the object (e.g., AES256).
--
-- * 'hoSSECustomerKey' - Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side​-encryption​-customer-algorithm header.
--
-- * 'hoRequestPayer' - Undocumented member.
--
-- * 'hoIfModifiedSince' - Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).
--
-- * 'hoPartNumber' - Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
--
-- * 'hoRange' - Downloads the specified range bytes of an object. For more information about the HTTP Range header, go to http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.
--
-- * 'hoIfUnmodifiedSince' - Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).
--
-- * 'hoSSECustomerKeyMD5' - Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure the encryption key was transmitted without error.
--
-- * 'hoIfNoneMatch' - Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).
--
-- * 'hoBucket' - Undocumented member.
--
-- * 'hoKey' - Undocumented member.

--
-- * 'horsRequestCharged' - Undocumented member.
--
-- * 'horsPartsCount' - The count of parts this object has.
--
-- * 'horsETag' - An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL
--

--
-- * 'horsContentLength' - Size of the body in bytes.
--
-- * 'horsExpires' - The date and time at which the object is no longer cacheable.
--
-- * 'horsRestore' - Provides information about object restoration operation and expiration time of the restored object copy.
--
-- * 'horsExpiration' - If the object expiration is configured (see PUT Bucket lifecycle), the response includes this header. It includes the expiry-date and rule-id key value pairs providing object expiration information. The value of the rule-id is URL encoded.
--
-- * 'horsDeleteMarker' - Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.

--
-- * 'horsMissingMeta' - This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.
--
-- * 'horsWebsiteRedirectLocation' - If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.

--
-- * 'horsSSEKMSKeyId' - If present, specifies the ID of the AWS Key Management Service (KMS) master encryption key that was used for the object.
--
-- * 'horsContentEncoding' - Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
