[squid-users] a keepalive problem about NTLM authentication pass through

Hi,

There may be a situation which we can't pass through HTTP with NTLM
authentication bacause of lack of keepalive.

 cache_peer XXX.XXX.XXX.XXX parent 8080 0 no-query connection-auth=on
 always_direct allow all

In above case, squid does not output "Proxy-Connection: keep-alive"
to cache peer host, bacause

> http.c:HttpStateData::sendRequest()
>
> 1998 /*
> 1999 * Is keep-alive okay for all request methods?
> 2000 */
> 2001 if (orig_request->flags.must_keepalive)
> 2002 flags.keepalive = 1;
> 2003 else if (!Config.onoff.server_pconns)
> 2004 flags.keepalive = 0;
> 2005 else if (_peer == NULL)
> 2006 flags.keepalive = 1;
> 2007 else if (_peer->stats.n_keepalives_sent < 10)
> 2008 flags.keepalive = 1;
> 2009 else if ((double) _peer->stats.n_keepalives_recv /
> 2010 (double) _peer->stats.n_keepalives_sent > 0.50)
> 2011 flags.keepalive = 1;

I think that we have to insert the following code

    else if (_peer->connection_auth == 1)
        flags.keepalive = 1;

What do you think ?

Squid version: 3.1.1

Sincerely,
