I've tried quite a few ways of setting the Cache-Control metadata and am unable to do so in a way that is reflected in the object response's Cache-Control header. I feel like I've got to be doing something wrong, as this is probably one of the more common headers to set for objects.
When I try to set it on the file's metadata during upload, it never seems to get set.
bucket.upload(source, {
destination: dest,
gzip: true,
metadata: {
'Vary': 'Accept-Encoding',
'Cache-Control': 'public, max-age=14400'
}
}, done)curl --head call for the file:

I seem to get back the default Cache-Control value here, and when viewing the file in the Google Cloud UI I see:
I then tried calling file.setMetadata() after the upload:
file.setMetadata({
metadata: {
'Cache-Control': 'public, max-age=57600'
}
}, done)... and I get the following:
Notice the same default value for Cache-Control, but the appropriate value for x-goog-meta-Cache-Control.

In the UI:
I've tried in a bucket with default object permissions as readable by public, and with setting the actual acl on the file during upload as readable by public, but see the same results. Any help would be greatly appreciated.
