From 46bf7996f43a4c47b00dde6d127d50f9faea9dd9 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Wed, 24 Feb 2016 13:47:57 +0100 Subject: [PATCH] Curl_read: check for activated HTTP/1 pipelining, not only requested ... as when pipelining is used, we read things into a unified buffer and we don't do that with HTTP/2. This could then easily make programs that set CURLMOPT_PIPELINING = CURLPIPE_HTTP1|CURLPIPE_MULTIPLEX to get data intermixed or plain broken between HTTP/2 streams.
