WP Super Cache and Cloudfront

Hello,

New to WP Super Cache Cloudfront and looking for some basic information and advice. I have had absolutely no success in finding any usable information on this on the amazon website…. really frustrating!

I am using self hosted wordpress (namecheap) using wp super cache with cloudfront as a cdn.

I am totally stumped as to how to use cloudfront to deliver https: content

For example sake my domain is http://www.domain.co.uk

I do not have an ssl for this domain
Do I need an ssl certificate to have my cloudfront content delivered as https: ? If I do, what settings do I need to use with cloudfront
Can I deliver ssl content using cloudfront where the user is forced to use https to access my non-https content? Again, if not – what settings do I need

Wordpress General Settings:

WordPress Address (URL): do I need to put https://www.domain.co.uk or http://www.domain.co.uk
Site Address (URL): do I need to put https://www.domain.co.uk or http://www.domain.co.uk

WP Super Cache

Site URL: do I need to put https://www.domain.co.uk or http://www.domain.co.uk
Off-site URL: do I need to put https://cloudfront.domain.co.uk or http://cloudfront.domain.co.uk
Additional CNAMES do I need to put the cname used for the cpanel here or just leave blank?

Any information, suggestions or links very welcome.

Thanks
