This article cover how to redirect non-www domain to www while using S3 bucket static hosting and CloudFront. As everyone might know about how to redirect/rewrite non-www to www using `.htaccess` in apache server. 

```
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
```
