When implemented by an exception class, indicates the network exception is connection level
(not application protocol level), so that the connection is no longer valid and will be closed.

Connection level network exceptions (timeout errors, unparseable server responses,
socket exceptions, etc) make it impossible to continue using an existing connection.
In contrast, application level network exceptions (such as negative responses from
the server) do not require immediate disconnect. For instance, if login failed due to
incorrect user account name and/or password, the connection may still be valid, and
another login/password may be tried without reconnecting to the server.
