With the existing AMQP drivers for PHP, applications can not currently maintain consistent connections and publish across application executions, instead they connect, publish and disconnect. �Vorpal Bunny is intended to reduce the overhead on the RabbitMQ server and the PHP application by using the jsonrpc-channel plugin, which maintains its own channels per session inside RabbitMQ's running instance, �eliminating most of the AMQP protocol overhead for one off message delivery.</span></font></div>

</span></div><div><span style="font-family:helvetica, arial, freesans, clean, sans-serif;line-height:20px">The design tries to employ PHP's APC cache if available to keep one session with the RPC server active per Apache server on the RabbitMQ server. Application flow is as follows:</span></div>

<div><span style="font-family:helvetica, arial, freesans, clean, sans-serif;line-height:20px">��3. On subsequent calls, call publish will send without trying to establish a session and then look for an error indicating the session has timed out or is no longer available. If this is the case, re-establish the session and retry the delivery.</span></div>
