That kind of caching is actually extremely rare in my experience. It&#x27;s difficult to set up for all but the most simple static sites, and since it isn&#x27;t available by default the vast majority of sites don&#x27;t bother.<p>The times I&#x27;ve implemented full-page caching (generally using Varnish) I&#x27;ve set it up so nginx runs in front of Varnish handling SSL termination, which means that I still have SSL support even though I&#x27;m serving through a cache.
