STOMP and Failover transport

[Valerio VALDEZ Paolini <va...@staff.dada.net>]

Hi All,

I'm working on an improved STOMP client written in Perl and I need some 
clarifications about the behaviour of the failover transport.

Let's suppose that a client, configured to use two hosts in failover A and B, 
opens a TCP connection to broker A, connects, subscribes to some destinations 
and then waits for incoming messages.

Let's suppose now that broker A is switched off, is it correct that, after 
connecting successfully to broker B, the client re-connects, subscribes again 
to all previously subscribed destinations and then tries again to receive 
messages?

Is there any case in which a failover shouldn't try to restore the situation 
before the transport failure?

Thanks,

        Valerio

I believe Ramit Arora and Simon Wistow from this list are also working separatly on failover transport for Net::Stomp and have access to PAUSE for uploading to CPAN.  It might be worth pinging them to avoid duplication of effort and get a One True Module(tm) out for the perl community.

(Speaking as a party who wants a Net::Stomp with failover and doesn't have the cycles to do it.  :P)
