When you request a video on Youtube, its web servers send two new HTTP
headers to the browser :
alt-svc
alternate-protocol
suggesting to the browser to switch to the new protocol QUIC.
Unfortunately
1) QUIC, working over UDP, is not cacheable by squid 3.4
2) even if cacheable, IT admins have to upgrade many tools to support and
account videos over QUIC ( proxy, firewall, bandwidth shaping, etc... )
See :
http://wiki.squid-cache.org/KnowledgeBase/Block%20QUIC%20protocol
We want to disable QUIC, so the servers and browsers fallbacks to normal
HTTP for videos.

I asked in another thread
3) support for Alternate-Protocol HTTP header.
Amos' answer :
As for #3, the Alternate-Protocol header patch is just automating these
squid.conf settings, which you can use explicitly in any Squid version:
acl AP rep_header_regex Alternate-Protocol .
reply_header_access deny AP
With that syntax :
squid3 -k reconfigure
2015/12/31 14:34:21| FATAL: Invalid ACL type 'rep_header_regex'
FATAL: Bungled /etc/squid3/squid.conf line 43: acl AP rep_header_regex
alternate-protocol .
Squid Cache (Version 3.4.8): Terminated abnormally.
CPU Usage: 0.016 seconds = 0.008 user + 0.008 sys
Maximum Resident Size: 37936 KB
Page faults with physical i/o: 0
Is it rep_header, not rep_header_regex ?
Is it reply_header_access with 3 parameters ?
From
http://www.squid-cache.org/Versions/v3/3.4/cfgman/reply_header_access.html
Usage: reply_header_access header_name allow|deny [!]aclname ...
Which is the correct syntax to suppress in the replies these headers ?
alt-svc
alternate-protocol
