Design question(Connector)

[Joao <jo...@wireless-networks.com>]

  Sorry for this new buy question...
    I have a server(kinda proxy) that connects to two connection upstream .
    In fact, it will connect to the second socket only if the first 
socket goes down.
    The second connection/socket is more of a failover option.


  Is a future like this already implemented in mina?

  Is there an easy way to implement it using the present connector 
infrastructure?

  Thanks in advance,


Joao,

interesting... you want to fail-over when writes fail?

my initial suggestion is to just set a Callback on the WriteFuture  
you get after IoSession.write() that does the fail-over logic when  
the first server goes down. That's the best existing infrastructure  
that we've got for achieving this, based on my understanding of what  
you want to do..
