Squid 5 now builds and installs perfectly on Gentoo Linux with a few custom changes to the distro's package installation script. I hope the devs will include these changes so Squid 5 can be readily available to everyone.
BTW it "makes" in parallel fine with -jx where x > 1, so no issues there either.

So, coming back to the original post: websockets.

I added this to Squid 5:

http_upgrade_request_protocols OTHER allow all

Am I right if I state that this should allow any protocol not just WebSockets?
In other words, I do not need to be specific with 'http_upgrade_request_protocols WebSocket allow all' unless I want to, right?

Unfortunately, after reloading Squid 5 the client browser still states the same:

The connection to wss://ed1lncb65702.webex.com/direct?type=websocket&dtype=binary&rand=1602769907574&uuidtag=9E73C14G-1580-43B4-B8D4-91453FCF1939&gatewayip=MY_IP_ADDR was interrupted while the page was loading.

And in access.log I can see this:

What does NONE_NONE/000 mean?

Where can I go from here?
What can I try to debug this further?
