Good Morning

I wonder if anyone tried to install a squid behind to ISA Proxys with ntlm_auth.
Iis it possible ? Something like this

Squid <---> ISA Proxy Country 1 <-----> ISA Proxy Country 2 <----> WWW

With authentication forward ?
I'm using Squid Cache: Version 2.6.STABLE4 with ntlm_auth without success.
