A proxy to automatically add CORS headers, supports:

• Simple requests with Access-Control-Allow-Origin: "*"
• preflight requests for non-simple requests.
• POST/PUT requests with body.
• CORS requests with credentials included.

There's an auto-cors service deployed at cors.harttle.com. Both HTTP and HTTPS are supported:

• http://cors.harttle.com/https://example.com
• https://cors.harttle.com/https://example.com

AutoCORS-Cookie header

Set Cookie when forward, cookie is not allowed to be set for fetch

fetch("https://cors.harttle.com/https://example.com", {
