You should use Haproxy in a Fail-over setup. Squid is great but it’s possible that Haproxy does this much better theses days then Squid. You can leave the authentication on the Squid servers and use the Haproxy as TCP Load balancer. If you need the clients Original IP address you can use the PROXY protocol to send these details between the haproxy and squid.

Subject: Re: Squid with more than 128 ports? Hey Anthony, Giving this a second thought, I believe I didn't explain myself correctly. I have 5 Squid servers, each listening on 80 ports, I would like to add another Squid server in the middle of the client and these servers to authenticate users before sending them to their ports. I already have ACL controls and auth control tools which I wrote and are working fine. My question is regarding how to configure this, I have found this configuration online but I am not sure how it will work performance-wise with 500+ proxies (could be 1000s in http_port 3128 name=port_3128
http_port 3127 name=port_3127
nonhierarchical_direct off
acl port_3128_acl myportname port_3128
acl port_3127_acl myportname port_3127
always_direct deny port_3128_acl
always_direct deny port_3127_acl
never_direct allow port_3128_acl
never_direct allow port_3127_acl
# 3128
cache_peer proxy1 parent 3128 0 proxy-only default name=proxy3128
cache_peer_access proxy3128 allow port_3128_acl
cache_peer_access proxy3128 deny all
# 3127
cache_peer proxy2 parent 3128 0 proxy-only default name=proxy3127
cache_peer_access proxy3127 allow port_3127_acl
cache_peer_access proxy3127 deny all
Combine these 2000+ lines in squid.conf with 2 external ACLs and a custom authenticator, can this cause a hit on performance or should it be no problem for squid to handle? On Thursday 10 December 2020 at 13:02:19, roee klinger wrote:

What do you mean by that? What are you using 400 ports for?

What authentication method / protocol do you want to use?

I think the best starting point is to ask what sort of authentication you want
to perform (ie: what is the authoritative system which holds the information
about who can authenticate and who cannot), then you can decide on the best
software to use to do that in front of Squid.

Under UK law, no VAT is charged on biscuits and cakes - they are "zero rated".
Chocolate covered biscuits, however, are classed as "luxury items" and are
subject to VAT. McVitie's classed its Jaffa Cakes as cakes, but in 1991 this
was challenged by Her Majesty's Customs and Excise in court.
The question which had to be answered was what criteria should be used to
class something as a cake or a biscuit. McVitie's defended the classification
of Jaffa Cakes as a cake by arguing that cakes go hard when stale, whereas
biscuits go soft. It was demonstrated that Jaffa Cakes become hard when stale
and McVitie's won the case.
