Head HTTP Request using Curl to Test Amazon Cloudfront Configuration

You can use Curl with -I switch to test if the Cloudfront configuration is working. You can see that when I hit media subdomain, the first time it misses the Cloudfront, the next request hits the Cloudfront. This means Cloudfront is configured properly.
