[squid-users] ICP vs Cache Digest

Hello all,

something I do not understand .. I plan enabling ICP between my squid
proxy web caches hosted in internal lan area and my internet gateways
hosted in dmz area.

Everything seem to work correctly, I see the ICP packets exchanged
between all devices except I always receive this type of error message
...

        2009/04/27 16:59:27| temporary disabling (Forbidden) digest from
10.66.9.193

Let we have a look on the configs in place ... All package installed are
compiled with '--enable-cache-digests'.

Squid (2.6.12 & 2.7.4) dmz internet gateways config ...

icp_port 3130
log_icp_queries off
icp_hit_stale off
icp_access allow srcip_internalproxies
icp_access deny all

Squid (2.6.12) internal Proxy web caches config ...

icp_port 3130
icp_query_timeout 0
maximum_icp_query_timeout 50 # (milliseconds)
dead_peer_timeout 1 second
log_icp_queries off
icp_hit_stale off
icp_access deny all

cache_peer @my_cache_parent_1@ parent 8080 3130 weight=2
cache_peer @my_cache_parent_2@ parent 8080 3130 weight=1

Is that normal I get this message or is there something I did not
understand with ICP and digest (e.g. not compatible) ??

Did I forget to add some parameters next to my cache_peer entries (e.g
no-digest ..) ?

many thks to help me.
Vincent
