Redirect S3 URL to Domain URL

I think what you're asking is that you want http://xyz.com/images/ to be hosted in S3 while your website is still hosted on your server. Is that correct?

If so, you can't have your server (xyz.com) and the S3 bucket with the same DNS name. You can create a bucket which is (say) images.xyz.com and then reference that from your server in your webpages.

If your whole site is being moved to S3 then I would strongly recommend that you use CloudFront because you get HTTPS support and the ability be much more flexible with redirects.
