Hi,
 i have this warning when starting ./squid,
 # ./squid
 2013/06/10 08:52:08| SECURITY NOTICE: auto-converting deprecated "ssl_bump allow <acl>" to "ssl_bump client-first <acl>" which is usually inferior to the newer server-first bumping mode. Update your ssl_bump rules.

 Chain FORWARD (policy ACCEPT)

 Chain OUTPUT (policy ACCEPT)

 I want this as a proxy to log all traffic JUST for log with VISITED URLs, If you know can propose any other config :)

 Thanks in advance
