[rabbitmq-discuss] properties.headers in Perl client

Wed Dec 22 00:24:33 GMT 2010

Net::RabbitFoot lets you set the headers as well. Take a look at how I do it @ https://github.com/LegNeato/bugzilla-push/blob/master/Push/lib/Backend/AMQP.pm#L127 (though I am not sure I actually pass any headers anywhere for that backend).

The code in RabbitFoot is @ https://github.com/cooldaemon/RabbitFoot/blob/master/lib/AnyEvent/RabbitMQ/Channel.pm#L275

Thanks,
Christian
