Setup a Raspberry Pi with squid and I only need a single site cached - https://code.org. I viewed the access.log and see the activity but 99% of entries are tcp_tunnel200 or tcp_miss and the site doesn't perform any faster. How can I get this site to be cached so our mobile users on slow hotspot internet can use this website? We have a cart with 24 laptops using a mobile router trying to simultaneously use this one site.
Thanks for any help anyone can provide.
