I have them off. My squid.conf as below....
~~~~~~~~~~
client_persistent_connections off
server_persistent_connections off
~~~~~~~~~~

Chris, if possible, can you pls share your acl rules for "tcp_outgoing_address".
Just want to make sure my rules are correct.
I tried with 2 nics and it did not work.

Also, I have to manage 5 ISPs.
I do not have the possibility of adding 5 lan cards in my server.

I read on the net that IPTables and route2 do not support virtual interfaces.

Looks like I have limited / no options here.

Thx.

Vai
