We are trying to implement proxy protocol (for use with RabbitMQ AMQP) and have this irule:

when CLIENT_ACCEPTED{
    set proxyheader "PROXY TCP[IP::version] [IP::remote_addr] [IP::local_addr] [TCP::remote_port] [TCP::local_port]\r\n"
}
when SERVER_CONNECTED {
TCP::respond $proxyheader
}

But keep receiving a logged error: 

TCL error: /Common/rabbitMQ_proxy_protocol  - Operation not supported (line 1) invoked from within "TCP::respond $proxyheader"

This page below says that TCP::respond is a valid command for SERVER_CONNECTED. Any ideas?
