Andrew Gaul commented on JCLOUDS-578:
-------------------------------------
I believe we should add another setter and getter for CORS to
{{MutableObjectInfoWithMetadata}} then swizzle it to
{{Access-Control-Allow-Origin}} in {{BindSwiftObjectMetadataToRequest}} as we
do for {{ETag}} and {{X-Delete-At}}. Generally jclouds does not allow setting
headers other than the user metadata.
> Custom HTTP Headers in Rackspace SwiftObjects are ignored

> Key: JCLOUDS-578
> URL: https://issues.apache.org/jira/browse/JCLOUDS-578
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-blobstore
> Affects Versions: 1.7.1
> Reporter: Daren Klamer
> Priority: Minor
> Labels: rackspace
>
> Rackspace allows users to set custom HTTP Headers on their files that are
> being served. This is especially useful for web fonts, as some browsers
> refuse to use the fonts unless the following header is set (more info
> [here|http://davidwalsh.name/cdn-fonts]):
> {{Access-Control-Allow-Origin: *}}
> Upon getting a SwiftObject from my Rackspace CloudFilesClient object and
> calling {{getAllHeaders().put( "Access-Control-Allow-Origin", "*" )}} I could
> see that the header was being lost and not sent with the underlying HTTP
> request.
> As a workaround here I patched
> [{{org.jclouds.openstack.swift.binders.BindSwiftObjectMetadataToRequest}}|https://github.com/jclouds/jclouds/blob/master/apis/swift/src/main/java/org/jclouds/openstack/swift/binders/BindSwiftObjectMetadataToRequest.java].
> Instead of simply binding the blob to the request and returning it (lines 86
> + 87), I changed it to bind the blob, then added all headers from the blob to
> the request.
> {{Blob blob = object2Blob.apply( object );}}
> {{request = mdBinder.bindToRequest( request, blob );}}
> {{return ( R ) request.toBuilder().replaceHeaders( blob.getAllHeaders()
> ).build();}}
