Detailed Description

Store data about the physical and logical attributes of a connection.

Some link state can be inferred from the data, however this is not an object for state data. But a semantic equivalent for FD with easily accessible cached properties not requiring repeated complex lookups.

Connection properties may be changed until the connection is opened. Properties should be considered read-only outside of the Comm layer code once the connection is open.

These objects should not be passed around directly, but a Comm::ConnectionPointer should be passed instead.

◆ nfConnmark

Netfilter CONNMARK value previously retrieved from this connection In case of FTP, the CONNMARK will NOT be applied to data connections, for one main reason: the CONNMARK could be set by a third party like iptables and overwriting it in squid may cause side effects and break CONNMARK-based policy. In other words, data connection is related to control connection, but it's not the same.
