What strategy should I take when I want to serve different data to different users with (Blitz) cache? Logged in users get one set of prices (that can vary depending on their price group memberships), users that are not logged in don't see prices at all.
I read and implemented a test of Dynamic Content as described in the Blitz Cache documentation, and the result looks promising. Lighthouse says between 97-99 on performance with a 0,6s Fist Contentful Paint, serving gzipped caches from Blitz Storage on the Hyperlane VPS (I will test Cloudflare too).
The question is rather about the potential user experience of having the prices ajaxed into the body of the html document. I've never seen any site do it this way before. Have a look at the result. Pay attention to how the prices appear and the related network events on the right:
(I realize that the
defaultPrice is passed as a parameter to the
productPrice template, and therefore the price is exposed - I've later replaced it with an encrypted string using the free plugin Cryptographer)
