title: Express + Jade rendering - client or server side?
body: <p>I just started using ExpressJS and Jade and I was sure that everything is server-side but this post makes me a little bit confused(because my site behaves like Client-side scenario): <a href="https://stackoverflow.com/a/12291675">https://stackoverflow.com/a/12291675</a> </p>
  
  <p>I guess that node.js only sends whole site once and then sends JSON data, because the rest is loaded in browser cache?</p>
  
  <p>So it would be helpful if someone describe this mechanism to me.</p>
