Setting proxy.connection.backend_ndx?

I want to share 1 backend connection between 2 application connections. Meaning, there is only one connection between the proxy and the backend, but there are 2 connections between the application and the proxy.

1. The first connection connects to the backend, and I don't do anything.

2. When the second connection connects to the proxy, I intercept with connect_server() and send it this:

proxy.response = {
type = proxy.MYSQLD_PACKET_RAW,
packets = {
proto.to_challenge_packet({
server_status = 2,
server_version = 50132,
thread_id = 12345678922222
})
}
}

3. When a query comes for the second connection, I try to give it the address of the backend: proxy.connection.backend_ndx = 1, so that it can use the established connection. However I get this error:

2009-07-13 13:36:00: (critical) proxy-plugin.c.1129: I have no server backend, closing connection
2009-07-13 13:36:00: (critical) network-mysqld.c.1188: plugin_call(CON_STATE_READ_QUERY) failed


Does anyone know what I'm doing wrong?

EDIT: I'm using 0.7.2, for reference.
