title: Do I need a SSL certificate for a domain if it redirects?
body: <p>If www.example.com redirects to example.com, do I need to have a SSL certificate for www.example.com? </p>
  
  <p>I'm asking because I'm renewing SSL certificates for my business and would need to buy new certificates for the www domain and don't want to expend the extra cost if it's unnecessary.</p>
  
  <p>More specifically, my load balance layer is NGINX and www.example.com is rewritten to <a href="https://example.com/%7Bparams%7D" rel="nofollow noreferrer">https://example.com/{params}</a></p>
