[squid-users] Login/Pass from squid to Squid

[FredB]

Hello,

I wonder if Squid can pass different login/password to another, depending to an ACL ?
I mean: 

1) a client connected to Squid without any identification helper like ntlm, basic, etc ...
2) an ACL like IP src, or browser, header, ... forward the request to an another squid with a login/passwd, but the login is different for each match (IP A = user1, IP B = user2, etc)
3) the second squid match login an allow the request

I can do something like that ?

Regards 
Fred
