Access to the referral object can potentially have us return a redirect response, or actually return the data. The latter is somewhat similar to swift static large objects (with the slight difference that we only refer to a single object here), for which we have a pending pull request open. The redirect does look somehow like the static website feature, for which we're also in a review process. Probably extending the swift slo feature to be supported in S3, and have add special api that will only have it point to a single object is a good way to proceed. Later we can have it redirect if the object that is referenced resides in a different region. Just sending a redirect to everything will make it simpler, any reason to go with the more complicated solution (performance is an obvious one)?
