title: How can I add a word before your domain name on a website?
body: <p>I don't know if this is relevant, but I am using Django to build a website.</p>
  <p>How do you add a word before your domain name? For example, with locations: <em>location.website.com</em>, similar to how <a href="https://en.wikipedia.org/wiki/Craigslist" rel="nofollow noreferrer">Craigslist</a> has a different URL for every city. How do you do this?</p>
