title: How to paging the folders and files in swift object storage?
body: <p>I used the query parameters 'limit', 'marker', and 'end_marker'.
  The parameter limit with marker works well(ex ?limit=10&amp;marker=image.png) but when I try to use 'end_marker' to retrieve the previous page(ex ?limit=10&amp;end_marker=image.png), it doesn't work well.
  How can I get the previous page in swift object storage? </p>
