Apache on Ubuntu Linux For Beginners

You must set up your Apache web server to use SSL, so that your site URL is https:// and not http://. Sure, there are exceptions, such as test servers and lone LAN servers that only you and your cat use.

But any Internet-accessible web server absolutely needs SSL; there is no downside to encrypting your server traffic, and it’s pretty easy to set up. For LAN servers it may not be as essential; think about who uses it, and how easy it is to sniff LAN traffic.
