You can use the versions subresource to list metadata about all of
the versions of objects in a bucket. You can also use request parameters as selection
criteria to return metadata about a subset of all the object versions. For more
information, see Request
Parameters.
To use this operation, you must have READ access to the bucket.
GET /?versions HTTP/1.1 Host:BucketName.s3.amazonaws.com Date:dateAuthorization:signatureValue
This implementation of GET uses the parameters in the
following table to return a subset of the objects in a bucket.

Specifies the key in the bucket that you want to start listing
from. Also, see Type: String Default: None | No |
max-keys |
Sets the maximum number of keys returned in the response body.
The response might contain fewer keys, but will never contain
more. If additional keys satisfy the search criteria, but were
not returned because Type: String Default: 1000 | No |

Use this parameter to select only those keys that begin with
the specified prefix. You can use prefixes to separate a bucket
into different groupings of keys. (You can think of using

Assume you have the following keys in your bucket, example-bucket.

photos/2006/February/sample.jpg
photos/2006/March/sample.jpg
videos/2006/March/sample.wmv

The following GET versions request specifies the delimiter parameter with value "/".
GET /?versions&delimiter=/ HTTP/1.1 Host: example-bucket.s3.amazonaws.com Date: Wed, 02 Feb 2011 20:34:56 GMT Authorization: AWS AKIAIOSFODNN7EXAMPLE:0RQf4/cRonhpaBX5sCYVf1bNRuU=
The list of keys from the specified bucket are shown in the following response.
The response returns the sample.jpg key in a <Version> element.
However, because all the other keys contain the specified delimiter, a distinct
substring, from the beginning of the key to the first occurrence of the delimiter,
from each of these keys is returned in a <CommonPrefixes> element. The key
substrings, photos/ and videos/, in the
<CommonPrefixes> element indicate that there are one or more keys with these key
prefixes.
This is a useful scenario if you use key prefixes for your objects to create a logical
folder like structure. In this case you can interpret the result as the folders
photos/ and videos/ have one or more objects.

In this case the response will include only objects keys that start with the specified prefix. The value returned in the <CommonPrefixes> element is a substring from the beginning of the key to the first occurrence of the specified delimiter after the prefix.
