> Google, Wikipedia

Caching Google makes no sense beyond some static resources. Wikipedia can be made available off-line, just not by using a man-in-the-middle server. This may make sense for a school with limited connectivity to do.

You don't have the option to run legacy browsers and expect everything to work.

Just don't use a legacy proprietary OS if you want to go on-line with it. Either install a free (as in gratis, but libre makes sense too) operating system, pay for the windows upgrades, or scrap the computers.

Really? So you cannot make any sense of the idea of caching, say, news articles? Blog posts? Software documentation? StackOverflow Qs/As? The cached pages are 100% useless in your mind?

All of those are not Google. OP was probably thinking of SERPs.

I think lack of sleep got the better of me there, sorry :\ but I still don't see what the issue with caching search engine results is. Why shouldn't result pages be cached? I would totally want to cache them locally when on such a high-latency connection, especially when I can expect similar queries (like in a classroom).

Indeed.
