From a34495933e83c4c850308e3448a16160162eb65a Mon Sep 17 00:00:00 2001 From: Roeland Jago Douma <roeland@famdouma.nl> Date: Tue, 29 May 2018 11:10:07 +0200 Subject: Move caching logic to response This avoids having to do it at all the places we want cached responses. We can't inject the ITimeFactor without breaking public API. However we can perfectly overwrite the service (resulting in the same testable effect).
