Squid on Windows

No, this is not an exotic seafood/glass recipe. Yesterday (well, Tuesday evening) I was sent down to Poole to set up a caching proxy server for a customer... on Windows. Working with a Microsoft operating system is a little bit unusual in my open source support job, but hey, it pays the bills. It turned out to be surprisingly easy (or rather, my preparation had been sufficiently thorough). We'd budgeted the entire day to set things up - but I had Squid running by 9:20am, and was authenticating against Active Directory by 10am (with a choice of methods; single-sign on with NTLM or prompting the user for credentials)....
