A WebSocket proxy is provided in the AMQ Broker installation to translate AMQ Interconnect WebSocket traffic to TCP requests and responses for AMQ Console. If you use AMQ Interconnect, you should add an incoming listener dedicated to the proxy so that AMQ Console management traffic stays separate from incoming client traffic on the router.

After ENTMQIC-1886, there is no longer any proxy.
