Title:
  Uploads to a swift container failing with connection reset by peer or
  broken pipe

Status in Ubuntu Cloud Archive:
  Expired
Status in OpenStack Dashboard (Horizon):
  Expired

Bug description:
  Using the following provided by Ubuntu's Cloud Archive:
  - Swift (1.10.0)
  - python-swiftclient (1.6.0)
  - python-django-horizon (2013.2-0ubuntu1~cloud0)
  - Django 1.5.4

  How to reproduce:
  - Create a container "test"
  - Try to upload a file to the test container

  Horizon is able to create and delete containers.
  It is also able to delete objects but you are unable to upload files without a connection reset by peer (if the endpoint is SSL) or a broken pipe error (if the endpoint is HTTP).

  Using python-swiftclient on the same machine where horizon is
  installed will upload the file successfully regardless if the endpoint
  is SSL or not.

  I have tried to understand why python-swiftclient is able to upload a
  file while horizon cannot - without success, hence this bug report.

  Environment information:
  - nginx in front of proxy nodes. If the endpoint is HTTPS, nginx handles the SSL termination.
  - swift endpoint is https://swift.example.org:443 or http://swift.example.org:80 which corresponds to the nginx server
  - keystone PKI authentication
  - horizon (HTTP, no SSL) on a standalone server
  - swift-proxy on a standalone server
  - swift-container, swift-object and swift-account running on the same standalone server

  Full stack trace of an upload to a swift container through Horizon with the swift endpoint in SSL (https termination done by nginx):
