CORS Headers
|
|
============
|
|
|
|
Cross Origin RequestS or CORS allows the browser to make requests against
|
|
Swift from another origin via the browser. This enables the use of HTML5
|
|
forms and javascript uploads to swift. The owner of a container can set
|
|
three headers:
|
|
|
|
+---------------------------------------------+-------------------------------+
|
|
|Metadata | Use |
|
|
+=============================================+===============================+
|
|
|X-Container-Meta-Access-Control-Allow-Origin | Origins to be allowed to |
|
|
| | make Cross Origin Requests, |
|
|
| | space separated |
|
|
+---------------------------------------------+-------------------------------+
|
|
|X-Container-Meta-Access-Control-Max-Age | Max age for the Origin to |
|
|
| | hold the preflight results. |
|
|
+---------------------------------------------+-------------------------------+
|
|
|X-Container-Meta-Access-Control-Allow-Headers| Headers to be allowed in |
|
|
| | actual request by browser. |
|
|
+---------------------------------------------+-------------------------------+
|
|
|
|
When the browser does a request it can issue a preflight request. The
|
|
preflight request is the OPTIONS call that verifies the Origin is allowed
|
|
to make the request.
|
|
|
|
* Browser makes OPTIONS request to Swift
|
|
* Swift returns 200/401 to browser based on allowed origins
|
|
* If 200, browser makes PUT, POST, DELETE, HEAD, GET request to Swift
|
|
|
|
CORS should be used in conjunction with TempURL and FormPost.
