browser (user-agent) typically issues a `preflighted request
<https://developer.mozilla.org/en-
US/docs/HTTP/Access_control_CORS>`_ , which is an OPTIONS call
that verifies the origin is allowed to make the request. The
Object Storage service returns 200 if the originating URL is
listed in this header parameter, and issues a 401 if the
originating URL is not allowed to make a cross-origin request.
Once a 200 is returned, the browser makes a second request to the

X-Container-Write:
description: |
Sets a container access control list (ACL) that grants write access.
The scope of the access is specific to the container. The ACL grants
the ability to perform PUT, POST and DELETE operations on
objects in the container. It does not grant write access to the container
metadata.
The format of the ACL is dependent on the authorization system
used by the Object Storage service. See `Container ACLs

create the new object by copying the ``X-Copy-From`` object. The
value is in form ``{container}/{object}``. You must UTF-8-encode
and then URL-encode the names of the container and object before
you include them in the header. Using PUT with ``X-Copy-From``
has the same effect as using the COPY operation to copy an object.
Using ``Range`` header with ``X-Copy-From`` will create a new
partial copied object with bytes set by ``Range``.

object manifest object.
in: header
required: true
type: boolean
X-Storage-Policy:
description: |
In requests, specifies the name of the storage policy to use for
the container. In responses, is the storage policy name.
The storage policy of the container cannot be changed.
in: header
required: false
type: string
X-Symlink-Target:
description: |
Set to specify that this is a symlink object.
The value is the relative path of the target object in the
format <container>/<object>. The target object does not need to
exist at the time of symlink creation.
You must UTF-8-encode and then URL-encode the names of the
container and object before you include them in this header.
in: header
required: false
type: string
X-Symlink-Target-Account:
description: |
Set to specify that this is a cross-account symlink to
an object in the account specified in the value.
The ``X-Symlink-Target`` must also be set for this to
be effective.
You must UTF-8-encode and then URL-encode the account name
before you include it in this header.
in: header
required: false
type: string
X-Symlink-Target-Account_resp:
description: |
If present, and ``X-Symlink-Target`` is present, then
this is a cross-account symlink to
an object in the account specified in the value.
in: header
required: false
type: string
X-Symlink-Target_resp:

X-Trans-Id:
description: |
A unique transaction ID for this request. Your
service provider might need this value if you report a problem.
in: header
required: true
type: string
X-Trans-Id-Extra:
description: |
Extra transaction information. Use the ``X-Trans-Id-Extra``
request header to include extra information to help you
debug any errors that might occur with large object upload and
other Object Storage transactions. The server appends the
first 32 characters of the ``X-Trans-Id-Extra`` request header
value to the transaction ID value in the generated ``X-Trans-Id``
response header. You must UTF-8-encode and then URL-encode the
extra transaction information before you include it in the
``X-Trans-Id-Extra`` request header. For example, you can include
extra transaction information when you upload `large objects
<https://docs.openstack.org/swift/latest/api/large_objects.html>`_
such as images. When
you upload each segment and the manifest, include the same value
in the ``X-Trans-Id-Extra`` request header. If an error occurs,
you can find all requests that are related to the large object
upload in the Object Storage logs. You can also use ``X-Trans-Id-Extra``
strings to help operators debug requests that fail to
receive responses. The operator can search for the extra
information in the logs.

name must be from 1 to 256 characters long and can start with any
character and contain any pattern. Character set must be UTF-8.
The container name cannot contain a slash (``/``) character
because this character delimits the container and object name. For

``xml``, or ``plain``. The default is ``plain``. If you append
the ``format=xml`` or ``format=json`` query parameter to the
storage account URL, the response shows extended container
information serialized in that format. If you append the
``format=plain`` query parameter, the response lists the container
names separated by newlines.

required: false
type: string
multipart-manifest_delete:
description: |
If you include the ``multipart-manifest=delete``
query parameter and the object is a static large object, the
segment objects and manifest object are deleted. If you omit the
``multipart-manifest=delete`` query parameter and the object is a
static large object, the manifest object is deleted but the
segment objects are not deleted. The response body will contain
the status of the deletion of every processed segment object.
in: query
