From d844f2b9ff50cfa7bf7f5b445d9f7eed7e6c3015 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 25 May 2020 08:31:08 +0200 Subject: [PATCH] altsvc: fix parser for lines ending with CRLF Fixed the alt-svc parser to treat a newline as end of line. The unit tests in test 1654 were done without CRLF and thus didn't quite match the real world. Now they use CRLF as well.
