auto-cors

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

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

fetch("https://cors.harttle.com/https://example.com", {
    headers: {
        "AutoCORS-Cookie": "XXX"
    }
})

Will set a "Cookie: XXX" header when request is forwarded.
