Socket Application Question

[mgarton@xxxxxxxxxxxxxxx]

I have a socket application that receives messages from a data queue and 
send the message to a remote host via sockets.  Currently the application 
uses a single persistent socket connection.  However, the application 
needs to be changed so that sends messages to four different hosts for 
redundancy.  I am not sure the best way to switch between sockets.  The 
easiest way to change the application would be to just switch between 
sockets but each time I send a message it would have to wait to receive a 
reply before processing a new message.  That doesn't seem to be very 
efficient.  I would like to be able to send/receive messages on all four 
socket connections at the same time but I don't know how to do this.  I 
have very little socket programming experience so any help would be 
appreciated.
