HTTPS has become quite the standard for the delivery of most content. Without delivering content through HTTPS users will experience "mixed content" browser errors and have content no be loaded correctly because its being blocked by modern web browsers. With that said; isn't it time for the Magento platform to come up with a cache system implementation that supports HTTPS and is recommended for us (Full Page Cache is "not recommended" per Magento documentation)?
Having to need two web servers (Apache + NGINX as a reverse proxy) and configure them to work with an HTTP-only cache system of Varnish is quite complicated and seems to me is overdue for an overhaul / new solution.
