I was thinking of retrieving it 1 line at a time.
You already have to retransmit in case packets get lost and you already need
a sequence number so you can filter out delayed duplicates. The order isn't
a problem. You only ask for things one item at a time.
If you were going to spend a lot of time running this code over long slow
links, it might make sense to keep several packets in flight. I don't see
that being appropriate here.
Actually, it would be an interesting experiment to see the size distribution
of config files (with and without comments) and how many of them
would/wouldn't work in a single but fragmented UDP packet and/or what
fraction fit into a single non-fragmented packet.
These are my opinions, not necessarily my employer's. I hate spam.
