So I created a new default nginx/unicorn/rails droplet and then modified just the default homepage file (/home/rails/app/views/home/index.html.erb).

The change never showed up when I reloaded the page. Not in any number of browsers, not after emptying their caches. Today I found that the change DID show up after I restarted the unicorn service.

So my question is, why did that fix it, and why should it be necessary? I've reviewed the configuration files for both unicorn and nginx, and I can't see anything that should be causing the pages to be cached...
