How to disable SPDY in Google Chrome

Question

I'd like to know how to disable automatically using SPDY protocol in Google Chrome. I need to make some IDS related tests and for that purpose I'd like to temporarily access Twitter or Google using HTTP SSL and not SPDY.

Is there even an option to disable it in Chrome? I couldn't find anything on Google.

Regards!

Well, you just need to run chrome with SPDY support disabled, that's all! Like this:

"...\chrome.exe" --use-spdy=off

does nothing on my v40 build. this will become the same moving target we had for disabling referrer all over again... – gcb Oct 06 '14 at 20:03
You need do close all chrome instances before this will work. You can check this by opening this page: chrome://net-internals/#http2 – Karsten Aug 14 '15 at 09:48

you can check all the setting by going to chrome://flags/

and disable spdy there and relaunch chrome.

There isn't a spdy option in the flags panel. My Chrome version is 44.0.2403.107. – Fiona Jul 28 '15 at 05:49

As above, option does not exist in chrome://flags/ – Digs Aug 11 '15 at 15:29

I don't know why people are down-voting you. When you posted it in Jan 2015 it was there and it was removed (along with Async DNS) by Google in mid March 2015. – Nicholas Yost Mar 08 '16 at 18:44

You should probably provide something more than a registry key incase people don't know what they're looking at there. Also, as it's a registry key, it'll only work on Windows. – markwalker_ Jun 21 '16 at 17:35

This registry key may have existed in an earlier version, but does not exist for me. Chrome Version 70.0.3538.110 (Official Build) (64-bit) – Joey Rizza Dec 14 '18 at 15:42

Maybe you can write something more for him? – mtszkw Sep 18 '15 at 18:00

This is a useless answer – Chad Schouggins Oct 07 '15 at 19:55
He means the Experimental QUIC Protocol option in chrome://flags. No idea if this actually disables SPDY though. Really wouldn't have hurt to mention where you find the option. – JDWardle Jan 10 '16 at 07:19
