<section1 topic='Introduction'>
|
|
<p>This document defines a module for &xep0062; that provides some basic conditions and actions to perform common packet filtering tasks.</p>
|
|
|
|
<p>This module operates in the "http://jabber.org/protocol/filter/basic" namespace.</p>
|
|
</section1>
|
|
|
|
<section1 topic='Conditions'>
|
|
<p>This module defines the fullowing conditions:</p>
|
|
|
|
<ul>
|
|
<li><message/> - true if the packet is a <message/> packet.</li>
|
|
<li><presence/> - true if the packet is a <presence/> packet.</li>
|
|
<li><iq/> - true if the packet is a <iq/> packet. If this element contains CDATA, then it must match the namespace of the first element inside the packet (typically <query/>) in order to be true.</li>
|
|
<li><to/> - true when the CDATA of this element matches the "to" attribute of the packet.</li>
|
|
<li><from/> - true when the CDATA of this element matches the "from" attribute of the packet.</li>
|
|
<li><type/> - true when the CDATA of this element matches the "type" attribute of the packet.</li>
|
|
</ul>

<section1 topic='Actions'>
|
|
<p>This module defines the fullowing actions:</p>
|
|
|
|
<ul>
|
|
<li><drop/> - drops the packet</li>
|
|
<li><bounce/> - bounces the packet with the error specified in the "code" attribute of this element.</li>
|
|
<li><redirect/> - redirects the packet to the JID specified in the CDATA of this element.</li>
|
|
<li><copy/> - sends a copy of the packet to the JID specified in the CDATA of this element, while giving the original packet to the user.</li>
|
|
</ul>
