I'm looking to move an existing website to Google Cloud Storage. However, that existing website has changed its URL structure a few times in the past. These changes are currently handled by Apache: for example, the URL /days/000233.html redirects to /days/new-post-name and /days/new-post-name redirects to /days/2002/01/01/new-post-name. Similarly, /index.rss redirects to /feed.xml, and so on.
Is there a way of marking an object in GCS so that it acts as a "symlink" to another GCS object in the same bucket? That is, when I add website configuration to a bucket, requesting an object (ideally) generates a 301 redirect header to a different object, or (less ideally) serves the content of the other object as its own?
I don't want to simply duplicate the object at each URL, because that would triple my storage space. I also can't use meta refresh headers inside the object content, because some of the redirected objects are not HTML documents (they are images, or RSS feeds). For similar reasons, I can't handle this inside the NotFound 404.html with JavaScript.
