[squid-users] Can I use an external ACL helper for "cache allow x" or "cache deny y" ?

[Eliezer Croitoru]

Thanks Alex,

I will start with a simple example which supports concurrency.
I will start with a Ruby+memcache\redis simple helper and will move on towards a full blown GoLang based one.

Yes, the "cache" directive supports "slow" ACLs, and an external ACL is
a slow ACL:
