Setting network properties

A destination contains a set of properties for defining client-server messaging behavior. The following example shows the network-related properties of a destination:

...
    <destination id="chat-topic">
        <properties>
            <network>
                <session-timeout>0</session-timeout>
                <throttle-inbound policy="ERROR" max-frequency="50"/>
                <throttle-outbound policy="REPLACE" max-frequency="500"/>
            </network>
    ...
        </properties>
    </destination>
...

Message Service destinations use the following network-related properties:

Property	Description
`session-timeout`	Idle time in minutes before a subscriber is unsubscribed. When the value is set to 0 (zero), subscribers are not forced to unsubscribe automatically.
`throttle-inbound`	The `max-frequency` attribute controls how many messages per second the server can receive. The `policy` attribute indicates what to do when the message limit is reached. A `policy` value of `ERROR` indicates that an error should be returned if the limit is reached. A `policy` value of `IGNORE` indicates that no error should be returned if the limit is reached.
`throttle-outbound`	The `max-frequency` attribute controls how many messages per second the server can send. The `policy` attribute indicates what to do when the message limit is reached. A `policy` value of `ERROR` indicates that an error should be returned if the limit is reached. A `policy` value of `IGNORE` indicates that no error should be returned if the limit is reached. A `policy` value of `REPLACE` indicates that the previous message should be replaced when the limit is reached.
