helper protocol in 3.4

[Markus Moeller]

Hi,

I am look at a way to provide information in addition to the username from 
the auth helper to the external acl helper

Can I use kv pairs in squid 3.4 ?  I see there is a kv pair group= . Does 
it mean the auth helper can return details which will be used by the 
external acl helper ?

Thank you
Markus
