Cache-Control / ETag headers about pokeapi HOT 2 CLOSED

can definitely add this to V2

from pokeapi.

Not sure if doing this would solve this issue, but when I try to make client side requests from Safari I get:
Failed to load resource: Request header field Cache-Control is not allowed by Access-Control-Allow-Headers.
XMLHttpRequest cannot load http://pokeapi.co/api/v2/pokemon/?limit=151. Request header field Cache-Control is not allowed by Access-Control-Allow-Headers.

I tried changing http to https, but that only worked for about 6-7 calls. Then it gave me this error again.

edit: forgot to mention it works great client side in Chrome.
