Is it possible to do that? I need to be able to access mydomain.com
by typing in my-domain.com
in the address bar of the browser?
Now I added a DNS entry:
my-domain.com CNAME mydomain.com
But this doesn't seem to work. I get an 404 not found error.
You can only map a single domain to your S3 bucket. However you could use Cloudfront to do this.
See my answer to another similar question for more information.
