This means you can use "lru", or any of the "heap" methods.

Usually squid will throw an error (or a least a warning) in the
cache.log if something is remiss.

You can put Squid wherever you like. The "--prefix" configuration
directive just specifies the "root" for the rest of the configuration
directives. So Squid will (unless directed otherwise on the command
line) look for its config file at c:\squid\etc\squid.conf

I can't really give informed answers when it comes to using Squid on
Windows, but in general, ufs is a fine choice for a lightly loaded
cache, aufs is better as the number of requests rise and coss (while the
new-kid-on-the-block) is a great supplement for small objects, in
conjunction with a aufs store. A null cache_dir is of course the
quickest, but it's write-only storage. :o)
