We appreciate the feedback. The load balancers and the Ceph RADOS gateways aren't running apache, so using the .htaccess specific code wouldn't work in this case.
To clarify, generating a .html file and uploading it to DreamObjects to host is possible, just not to have it auto load it like an "index.html" file (or whatever default index page) when visiting "alis.myowndomain.org". For example, I made a sample html page and uploaded it to the publictest bucket.
http://publictest.objects.dreamhost.com/ - will show just the xml output.
http://publictest.objects.dreamhost.com/index.html - will show you html page with clickable links.
So if you have code to generate the html page and upload it, and don't mind linking people specifically to the .html page created, this is a possible workaround.
