Summary
CloudFlare allows you to have up to 3 page rules for free, but it takes 1 page rule to force redirection to HTTPS for just one particular subdomain. You can get around this by actually adding the following rewrite config to the <VirtualHost> setup in your website's Apache .conf file.
This means that you can use Flexible SSL with CloudFlare and force your website to always redirect users to the HTTPS version.
