I want to set up a public wireless access point in a booth that I can let anyone download apps from Apple App Store via iPhone/iPod/iPad only. I don't want them to surf the web or anything except downloading apps.
I figured out that Squid-cache might be able to help by setting some kind of access list. But how do I know which kind of connection should I allow [e.g. block by ports? or some specific hostnames?]. Any idea please??
