When a connection is made between client and server how much network traffic
does the open connection create.
Can you get away with a array of connections that are connected but idle or
is it better to connect - do action - then dissconnect?
Programatically it would be easy to leave the connections up all the time
the apps are active even if no data transfer is taking place.
I am presuming this would cause a lot of traffic but I am wondering if it is
possible to get away with it?

Thanks
