From 9fa6bdb64e66f0175d2c3aa74e51f52858e119b9 Mon Sep 17 00:00:00 2001 From: silverwind Date: Mon, 6 Sep 2021 23:05:44 +0200 Subject: [PATCH] Add Cache-Control to avatar redirects (#16973) * Add Cache-Control to avatar redirects This does seem to do the trick to make the Avatar redirects cachable in Chrome. In Firefox, it does not seem to work, thought and I found no way to suppress the requests to the original URLs, I even tried setting an Etag to no avail.
