Caching patches with a Squid server?

[Moonleg]

You could download the patch on a single machine, then copy the installed game on top of the other installations on the other machines. That's what I do, and it works like a charm - the game just checks the registry to see that it actually IS installed (which would be a yes), not to confirm version or anything like that.

It won't help with reinstalls, obviously, but it should be a huge help for the initial expansion download.

that's actually what I currently do, I was trying to streamline things a bit. If I could get Squid to cache the update files, then the other XIV clients in the house would just pull from the local server, and they wouldn't even know it. It would all be completely seamless.
