[Java] Select the fastest mirror in a group of addresses

[Chavo]

When I was doing a bit of research (mostly to see if it had already been done), it appeared you can also auto-optimize mirrors using DNS.  Of course, that has to be done by the domain owner.  I don't think battle.net is doing this or my class above would be returning the first result nearly every time!

Not to mention, StarCraft wouldn't be acting the way it does. :P

@iago: If they closed the socket, or destroyed it, after receiving the first SYNACK, then the one would send an ACK and the rest would be ignored, right? I'm rather sure that's whats happening.

The Starcraft program doesn't know when it receives the SYNACK, all it knows is when the connection is "established". Don't forget that Starcraft operates on the application layer, where the concepts are connected/disconnected/etc. What you're thinking of is the TCP layer, where the states are SYN_SENT and SYN_RECEIVED and other lower level stuff.

So in other words, no, Starcraft isn't doing that. And plus, I've reversed that portion, and I assure you that it's just a naked, classic, connect() syscall.

spiffy, make sure you give yourself credit too!

That's what the $Id$ tag is for; it's roughly equivalent to "filename revision date author"
