Simple proxy server example

Usage:

$ go run proxy.go -proxyURL=<http://api.something.com> -port=<port>

port 9000 is used by default if not specified.

The proxy server will proxy calls from http://api.something.com to localhost:9000

Use cases

You need to modify an API but have no influence to do so.

For example:

• Your web app is on a https endpoint and the API is on http.
• You wish to add more headers to the API (such as cache-control)

You can host the proxy server on a https endpoint, make https calls and it'll return results from the http API.
