From ea3a5d07dc5d71306c60ad4fd2b8c2a3ccb57d6a Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 5 Dec 2017 08:39:31 +0100 Subject: conncache: only allow multiplexing within same multi handle Connections that are used for HTTP/1.1 Pipelining or HTTP/2 multiplexing only get additional transfers added to them if the existing connection is held by the same multi or easy handle. libcurl does not support doing HTTP/2 streams in different threads using a shared connection.
