From 6915d2fb2e88e0c339fe37b37ce14f5fe446c1c6 Mon Sep 17 00:00:00 2001 From: Sergey Kandaurov Date: Thu, 8 Jun 2023 16:56:46 +0400 Subject: HTTP/2: removed server push (ticket #2432). Although it has better implementation status than HTTP/3 server push, it remains of limited use, with adoption numbers seen as negligible. Per IETF 102 materials, server push was used only in 0.04% of sessions. It was considered to be "difficult to use effectively" in RFC 9113. Its use is further limited by badly matching to fetch/cache/connection models in browsers, see related discussions linked from [1]. Server push was disabled in Chrome 106 [2]. The http2_push, http2_push_preload, and http2_max_concurrent_pushes directives are made obsolete. In particular, this essentially reverts 7201:641306096f5b and 7207:3d2b0b02bd3d.
