CloudFront uses SSL:

https://d1t66zoqn9vlte.cloudfront.net/simple/

and the default cache retention is 24h if no cache headers
are provided.

These are the headers provided by CloudFront, first request:

200 OK
Content-Type: text/html; charset=utf-8
Content-Length: 1323539
Connection: keep-alive
Server: nginx/1.1.19
Date: Thu, 28 Feb 2013 13:56:22 GMT
Strict-Transport-Security: max-age=86400

X-Cache: Miss from cloudfront

Second request:

200 OK
Content-Type: text/html; charset=utf-8
Content-Length: 1323539
Connection: keep-alive
Server: nginx/1.1.19

The above setups are for testing, and not meant for deployment.
