/**
* The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if
* you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.
*
* A HEAD request has the same options as a GET action on an object. The response is identical
* to the GET response except that there is no response body. Because of this, if the HEAD request
* generates an error, it returns a generic 404 Not Found or 403 Forbidden code. It is not possible
* to retrieve the exact exception beyond these error codes.
*
* If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store
* the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
*
*
* -
x-amz-server-side-encryption-customer-algorithm
* -
x-amz-server-side-encryption-customer-key
-
*
x-amz-server-side-encryption-customer-key-MD5
*
*
*
* For more information about SSE-C, see
* Server-Side Encryption
* (Using Customer-Provided Encryption Keys).
*
*
*
* -
Encryption request headers, like x-amz-server-side-encryption, should not be sent for GET
* requests if your object uses server-side encryption with CMKs stored in Amazon Web Services KMS (SSE-KMS) or
* server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of
* keys, you’ll get an HTTP 400 BadRequest error.
* -
The last modified property in this case is the creation date of the object.
*
*
*
* Request headers are limited to 8 KB in size. For more information, see
* Common Request Headers.
*
* Consider the following when using request headers:
*
*
* -
Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are
* present in the request as follows:
*
* -
If-Match condition evaluates to true, and;
* -
If-Unmodified-Since condition evaluates to false;
*
*
* Then Amazon S3 returns 200 OK and the data requested.
* -
Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are
* present in the request as follows:
*
* -
If-None-Match condition evaluates to false, and;
* -
If-Modified-Since condition evaluates to true;
*
*
* Then Amazon S3 returns the 304 Not Modified response code.
*
*
* For more information about conditional requests, see RFC 7232.
*
* Permissions
<
*
* p>You need the relevant read object (or version) permission for this operation. For more information, see
* Specifying
* Permissions in a Policy. If the object you request does not exist, the error Amazon S3 returns depends on whether
* you also have the s3:ListBucket permission.
*
*
* -
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code
* 404 (\"no such key\") error.
* -
If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403
* (\"access denied\") error.
*
*
* The following action is related to HeadObject:
