<p>The connection is up.</p>
<p>This message informs the owner process that the connection or reconnection completed.</p>
<p>If Gun is configured to connect to a Socks server, then the connection is not usable yet. One or more <a href="../gun_tunnel_up">gun_tunnel_up(3)</a> messages will follow.</p>
<p>Otherwise, Gun will start processing the messages it received while waiting for the connection to be up. If this is a reconnection, then this may not be desirable for all requests. Those requests should be cancelled when the connection goes down, and any subsequent messages ignored.</p>
