That sounds like Raygun from Cloudflare and ESI (potentially) from Fastly. https://www.cloudflare.com/docs/railgun/intro.html https://www.cloudflare.com/docs/r

  ESI isn't from fastly.. it's an old W3C standard from 15 years ago. You have to markup all of your HTML to use it though. So Cloudflare made a nice improvement with Railgun, so that you don't need to markup your HTML.. but you have to setup and run railgun on your server, so it can compare the pages. (I don't think it does anything else other than basically diving up the page content so individual parts can be cached.. but someone from cloudflare is welcome to tell me I'm wrong.) To compare our tech to railgun: - there's nothing to setup or run (you just enable it for the zone), and you don't need to modify your pages (like you do for esi) - it works on all content, including binaries/images/etc - each page/file only needs to be analyzed once. So if a page is first seen in a request from Japan, a 2nd request from Germany would be accelerated, even though that PoP has never seen the page before. - Because of the way it works, it's paired with adaptive routing, which routes the data over the fastest active link between the pops.. so there's no handshake setup time, ssl negotiation time, etc over the long haul. When its enabled, we actually use it to transmit most content between the pops.. so it also accelerates revalidation of static content, etc. Edit: also it's not $200/mo.. it's just included with your account.
