This feature allows to have unlimited set of connections initiated from aiengine server to external servers.

Implementation Details

Planned but implemented:

Configuration

		<channel name="google" run="true">
			<property name="protocol" value="http"/>
			<property name="protocol.showmessages" value="false"/>
			<property name="protocol.showpackets" value="false"/>
			<property name="msgtype" value="text"/>
			<property name="permanent" value="true"/>
			<property name="host" value="www.google.com"/> 
			<property name="port" value="80"/> 
			<property name="redirect-in" value="true"/>
			<property name="redirect-out" value="true"/> 
			<property name="topic-in" value="http.response"/> 
			<property name="topic-out" value="http.request"/> 
		</channel>

How to Test
