title: Where do we put the HTTP Response Header stuff?
body: <p>I'm trying to put in the <code>Access-Control-Allow-Origin: *</code> statement into the HTTP Response Header, since that's what everything is saying to get past the CORs issue (I'm trying to code with p5.js). My question is: where exactly does this statement go and how do I get there? </p>
  
  <p>I can not find a basic answer anywhere and I can't really move on without it.

  Thank you!</p>
