Re: [squid-users] [RFC - Request for Comments] Removal of Squid external DNS helper API

Amos,

maybe if you create a googleForms (to populate a google spreadsheet)
or something like that you will be able to read results and maybe post
it in somewhere (just givin an idea).

BTW, we have here about 15+ squid servers (in several locations and
clients) and we dont use dnsserver helper.
