[squid-users] squid 3 as accelerator & backside digest auth

I got squid-3.0-PRE3-20060110 compiled OK. The intention I have is to
replace squid-2.5.STABLE3 to accelerate a backend .NET server.
There is a requirement to support digest authentication through to the
.NET server and 2.5 does not seem to support it - I think because the
backend request is using HTTP/1.0.

I had hoped 3.0 would support HTTP/1.1 and digest auth based on the
release notes, however there are some squid.conf directives which do not
seem valid in 3.0 even though they are in 2.5
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 48
unrecognized: 'httpd_accel_host virtual'
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 49
unrecognized: 'httpd_accel_port 0'
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 50
unrecognized: 'httpd_accel_single_host off'
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 51
unrecognized: 'httpd_accel_with_proxy off'
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 52
unrecognized: 'httpd_accel_single_host off'
2006/01/11 11:40:34.659| parseConfigFile: 'squid.conf' line 53
unrecognized: 'httpd_accel_uses_host_header on'

So to cut to the chase, my question is... can 3.0 be used as an
accelerator supporting digest auth on the backside? Or alternatively,
could this be supported in 2.5 if correctly configured?

Here is my squid.conf.
