Hello,
I have upgraded to squid 2.6 stable 2 on my debien server.
I use squid as an accelerator (and only this) in front of a http load
balancer.
My previous (obsolete) configuration was:
http_port 79
httpd_accel_host 161.3.50.16
httpd_accel_port 81
httpd_accel_with_proxy off
httpd_accel_uses_host_header off
Which I changed to:
http_port 79 defaultsite=161.3.50.16 vhost vport=81
As I want to accelerate http on port 81 on ip 161.3.50.16 where squid
listen to port 79.
When using it, I receive:
"The requested URL could not be retrieve
While trying to retrieve the URL: http://161.3.50.16:79/
The following error was encountered:
* Unable to forward this request at this time.
This request could not be forwarded to the origin server or to any
parent caches. The most likely cause for this error is that:
* The cache administrator does not allow this cache to make direct
connections to origin servers, and
* All configured parent caches are currently unreachable.

I read stable2 changes, expecially bug 1650 in tracker :
http://www.squid-cache.org/bugs/show_bug.cgi?id=1650
This is a known issue in stable1 that should be fixed in stable2. Can
you confirm as it is not for my configuration.
I also add that adding "always_direct allow all" does not solve my problem.
Here is my entire squid.conf if this helps:
