I was able to reproduce this bug in Chrome too. Download this file, then run the following command: `while true; do cat test.http | nc -l 8000 -q 0; done` then go to `http://localhost:8000` I have no idea why the reporter sais this doesn't reproduce in Fx56 - I managed to do it with this small test case and with a xpcshell-test. For what it's worth, the bug can be fixed at this [line](https://searchfox.org/mozilla-central/rev/55aa17110091deef24b913d033ccaf58f9c6d337/netwerk/protocol/http/nsHttpTransaction.cpp#1403), by removing the ' ' and '\t' cases. Also relevant to the conversation: https://lists.w3.org/Archives/Public/ietf-http-wg/2013JanMar/0249.html I don't know if we have other reports of this issue, but it seems we should fix it.
