What is this?

This is a simple Proxy server which fully bypasses CORS and allow the browser to query any API.

Why did I make this?

I found many CORS proxies, however, they simply added “Access-Control-Allow-Origin” to all requests. They did not respond to the CORS preflight requests. Without this, the API calls would fail.

How does it work?

• Responds to CORS preflight requests
  1. Default header values (configurable)
     • Access-Control-Allow-Origin = *
     • Access-Control-Allow-Method = *
     • Access-Control-Allow-Headers = *
     • Access-Control-Max-Age = 86400

2. Adds “Access-Control-Allow-Origin” to all responses
