Squid parent proxy config

[Hans du Plooy <hansdp-lists@sagacit.com>]

Hi guys,

I'm trying to make my squid look at an external proxy (to avoid going 
through the ISP's transparent proxy, which is blacklisted on some sites 
- slashdot, amongst others), but I'm not having eny joy.

I have this in my squid.conf:

cache_peer proxy.example.org parent 8080 3130
cache_peer_domain proxy.example.org slashdot.org

The parent proxy listens to both 8080 and 3128, but not to 3130.  If I 
don't add 3130, squid wouldn't start -gives me a configuration error.

I have no idea what the parent proxy runs, I suspect it's not squid, and 
I suspect it's an appliance type proxy/firewall.

I'm getting the following in my logs:

cache.log:
2005/08/07 23:16:34| temporary disabling (Forbidden) digest from 
proxy.example.com

access.log:
1123451586.585   3640 192.168.0.100 TCP_MISS/200 15655 GET 
http://slashdot.org/ - TIMEOUT_FIRST_UP_PARENT/proxy.example.com text/html

And while this is happening, I can still not post to slashdot :-(

However, when I set my firefox to look directly at the parent proxy, it 
works perfectly.  Or at least I'm not getting errors.  And I can post to 
slashdot...

Any ideas what is wrong?

Thanks
