Does it work  with keystone? I am trying to  test this feature.
Follow all your steps.. Always getting "No such file or directory"

Here how I am accessing

getting this error

Do I need to setup  anything to support this feature?

Thanks

Subject: [Openstack] [Swift] swift news and plans

TL;DR: removing code from swift, associated projects doc, swift 1.5.0

I want to let the openstack community know of some recent changes within
swift and how those changes will affect the next version of swift. Swift
has a growing developer community and a rapidly expanding deployed base.
While this growth is fantastic, it does come with new challenges,
especially for the swift core developers. As more and varied use cases
are presented to swift, patches are submitted that enhance swift's
functionality either by offering optional features or alternative APIs.

The challenge with this growth is that the core developers become
responsible for understanding and maintaining an ever-increasing
codebase. This responsibility becomes a timesink, both for reviews and
for fixing regression bugs as new core features are added. For non-core
developers, the review process for new code becomes slower, and changes
that don't affect swift's core functionality often fall to the bottom of
the pile--sometimes even to the point of expiring due to inactivity.

Our solution for these problems is to limit the scope of swift. Swift's
core functionality is to provide cheap, durable, and scalable object
storage exposed through its own API. Other functionality and alternative
APIs should be maintained separately from the swift codebase.

As a result of this focus in scope, we have begun removing some of the
optional parts of swift. Initially, this will include the tempurl,
formpost, staticweb, rate limiting, swift3, domain remap, and cname
lookup middleware modules. Proposed patches that offer alternative APIs
(like CDMI) or include optional functionality that can be implemented
external to swift will be encouraged to be developed separately from
swift.

We have already begun the process of removing many of these pieces of
middleware from swift and moving them into their own respective repos.

However, all of this functionality is quite valuable and beneficial to
swift. 
There is a real need for most of these modules. Separating them from
swift introduces the problem of discoverability. As a result, we have
added a new page to our swift docs that lists associated projects and
added links to that page on swift.openstack.org.

http://swift.openstack.org/associated_projects.html

This page is fairly limited right now, but the basic structure is there.
As things are removed from swift and as new associated projects are
created, they will be added to the list. This doc page is maintained in
the swift codebase, so updating it is subject to the same requirements
of any other patch to swift.

An important note is that this list offers no distinction or references
to "official" or "approved" associated projects. This list is
independent of any openstack CI integration that may or may not happen
in the future.

Once we finish the process of migrating the optional pieces of swift
away from the swift codebase, we will cut our next release: swift 1.5.0.
There is no date set  for this yet, but I hope the migration process can
be finished in the next several weeks. Swift 1.5.0, therefore, will be
somewhat larger than most of our other swift releases. Existing
deployers will need to be careful about upgrading to ensure that new
dependencies are met.

If you have any questions, please feel free to email me. This whole
effort is a work-in-progress. I know that there are several similar
discussions going on within the openstack community, and swift's
solution is not necessarily intended to replace any more general
solution that may eventually arise. If there is a better solution at
some point, we will do what we can to integrate with it.
