## Deployment

This project is written in [Cloudfalre Workers](https://workers.cloudflare.com/), and can be easily deployed with [Wrangler CLI](https://developers.cloudflare.com/workers/wrangler/install-and-update/).

```bash

wrangler publish

```

## Usage Example

```javascript

fetch('https://test.cors.workers.dev/?https://httpbin.org/post', {

  method: 'post',

  headers: {

    'x-foo': 'bar',

    'x-bar': 'foo',

    'x-cors-headers': JSON.stringify({

      // allows to send forbidden headers

      // https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name

      'cookies': 'x=123'

    }) 

  }

}).then(res => {

  // allows to read all headers (even forbidden headers like set-cookies)

  const headers = JSON.parse(res.headers.get('cors-received-headers'))

  console.log(headers)

  return res.json()

}).then(console.log)

```

Note:

All received headers are also returned in "cors-received-headers" header.

Note about the DEMO url:

Abuse (other than testing) of the demo will result in a ban.  

The demo accepts only fetch and xmlhttprequest.  

To create your own is very easy, you just need to set up a cloudflare account and upload the worker code.  

My personal thanks to Damien Collis for his generous and unique donation.
