Hi! Thanks a lot for sharing details about it, it's an ingenious app. :)

Could you please elaborate a bit on how you work with the TCP window size -- how might I set it to 0 and back? Do you simply use SO_RCVBUF or is there more to it?

If you happen to go through with making more variants of this, it would be amazing if you could make them open source as well (even just the backend). It's a clever idea that solves a very real problem!

Thank you! And I'd be happy to elaborate a bit more, although you already explained most of it yourself ;). Currently the server just stops reading from the socket and the rest is being handled by the networking stack (i.e. buffer fills up, window size is to 0). At this moment the buffer size is also fixed (it sits somewhere between having good throughput and not consuming too much memory for parked connections), but an improvement would be to change it dynamically to improve behavior on both fronts.

For any other versions or source releases I'll post an update!
