SearchGo Varnish 6 or go home!: that’s pretty much the message of this chapter.
Varnish has a big responsibility in terms of acceleration, stability, and content delivery. We cannot emphasize enough that being on a supported version is crucial.
Varnish Cache 6.0 LTS or Varnish Enterprise 6 are the versions you should use, and at this point, the reason why should be crystal clear.
We’re already two chapters into this book. We’re past the introduction phase, and all the disclaimers have been presented. You know what Varnish is; you know what it does. Now it’s time to start using it.
In chapter 3, we’ll be looking at how you can control Varnish’s behavior using conventional HTTP caching mechanisms.
