<section1 topic='Implementation Notes' anchor='impl'>
<p>Some XMPP clients do not respond to IQ stanzas containing unsupported payloads. Although this is in violation of &xmppcore;, this behavior can result in disconnection of clients that are in fact actively connected to the server.</p>
</section1>
<section1 topic='Security Considerations' anchor='security'>
<p>If a server receives a ping request directed to a full JID &LOCALFULL; associated with a registered account but there is no connected resource matching the 'to' address, <cite>RFC 3920</cite> requires it to reply with a &unavailable; error and set the 'from' address of the IQ-error to the full JID provided in the 'to' address of the ping request. If a connected resource receives a ping request but it does not want to reveal its network availability to the sender for any reason (e.g., because the sender is not authorized to know the connected resource's availability), then it too MUST reply with a &unavailable; error. This consistency between the server response and the client response helps to prevent presence leaks.</p>
