Investigate whether it's possible to create redirects on S3

[chrisroos]

We're hoping to redirect from the Asset Manager to a public asset on S3. If an asset is updated then we think we'll want to add a redirect from the old to new URLs.

It is possible to get an S3 object URL to respond with a 301 (temporary) redirect by setting the x-amz-website-redirect-location property in the object's metadata. You can redirect to another object in the bucket by setting this property to the new object key, or you can redirect to an arbitrary URL by setting the property to the new URL. See the "Configuring a Webpage Redirect" documentation.

If you configure an S3 bucket for "static website hosting" then you can setup more sophisticated routing rules, but I think that means we'd have to have an index page, so it's probably not going to be what we want.

I've just been trying out the "301 redirect" mechanism and it seems to only work if you enable "static website hosting" for the S3 bucket which I'm not sure we want to do.

I think these investigation tasks are "done", although we will need to decide how/whether we're going to handle updating assets. I plan to create a new issue or two to capture that.
