RE: Squid with webwasher using NTLM authentication

I've tried almost all options for cache_peer but it doesn't seem to work. Is it a squid's bug?

I'm currently using this line:
cache_peer comp parent 3128 3130 no-query default
For the moment there is no login credentials. I'm gonna check this.

Have you told Squid to trust the webwasher proxy with proxy login credentials? See cache_peer directive.

Maybe you need to upgrade to 2.7. But it depends on which exact 2.6 release you are using.. see below.

squid-3.0 does not support forwarding of NTLM authentication as it does not yet implement the required workarounds to Microsoft HTTP protocol violations needed to support NTLM forwarding.
