My issue is that once the first asynchronous call is made, the console app considers the program to be completed and terminates before the as...
I'm trying to optimize a tcp socket wrapper which is struggling with lots of inbound connections. I'm testing it within a basic chat server and a small client app to send clients to it. Both apps are on a separate W2k3 server connected by a gigabit switch. By trial and error I've refined my testing to 10 clients connecting at 100ms in...

I've looked at some of the apple core API stuff, as well as ASIHTTPRequest. It's made me curious - is there a simple way to just send a nonblocking request to a URL? I could do it what seems to be the standard way - make the request object, make a useless delegate object that just ignores the response, and that's how I've been doing it. ...
