--- Comment #11 from David Cook <dcook at prosentient.com.au> ---
Adam inspired me to test this, and I got a proof-of-concept working in Docker
using a Squid proxy. 

Here are the steps if someone wants to reproduce my efforts:

Windows:
1.      docker pull sameersbn/squid:3.5.27-2
2.      docker run --name squid --publish 3128:3128 sameersbn/squid:3.5.27-2
3.      docker cp squid:/etc/squid/squid.conf ./squid.conf.default
4.      cp ./squid.conf.default ./squid.conf
5.      sed -i 's/http_access deny all/http_access allow all/' ./squid.conf
6.      sed -i 's/http_access deny CONNECT/http_access allow CONNECT/'
./squid.conf
7.      docker stop squid
8.      docker rm squid
9.      docker run --name squid --publish 3128:3128 --volume
"/$(PWD)/squid.conf:/etc/squid/squid.conf" --net koha_kohanet
sameersbn/squid:3.5.27-2

Koha container:
1.      http_proxy=squid:3128 curl -v https://www.google.com
2a.     yaz-client connect:squid:3128,tcp:lx2.loc.gov:210
2b.     base LCDB
2c.     find test
2d.     show 1

3a.     Use ZOOM in a Perl script to connect to Squid proxy
3b.     This works (shows 10000 results connecting to LOC LCDB database and
searching for as title of ‘test’)
3c.     Script included below*

*
#!/usr/bin/perl
use ZOOM;
my $conn = new ZOOM::Connection('connect:squid:3128,tcp:lx2.loc.gov:210');
$conn->option( databaseName => 'LCDB' );
my $rs = $conn->search_pqf('@attr 1=4 test');
my $n = $rs->size();
warn $n;
