Edge-Side-Includes: How do esi:inline tags work

Question

I have been looking at the ESI (Edge-Side-Includes) specs, but I cannot quite figure out how esi:inline elements work. Can anyone explain that?

Answer 1

Finally, I figured it out. You send a response with an <esi:include> and in the reply to that one you include <esi:inline>-marked fragments for later re-use.

That is a pretty slick way to allow retrieval of many small pieces in one large request.
