We have a Delphi implementation with the RemObject superTCP channel with Binary messages.
It looks like, sometimes our server gets messages twice and also handles them twice. After looking into the code, I saw the AckWaitYimeout on the client was set to 2000 (ms). I know the customer has a poor network connection from the location this action was initiated.
Can this low time cause messages are sending twice to our server?
Is there some best practice to prevent this kind of errors? Of course increasing the timeout client side is an option, but maybe there’s also an server side option? I think of checking (per session) the incomming message id’s (and cache time for a time X) to see if we have dupplicates
