A shitty TCP proxy that relays all requests to a local port to a remote server.
portproxy -port 8080 -raddr google.com:80
Will proxy all TCP requests on localhost:8080 and send them to google.com.
If the http flag is given:
portproxy -http -port 8080 -raddr google.com:80
The proxy will attempt to detect HTTP requests. If a HTTP request contains an
Origin header, the response from the remote server will be modified to
include a Access-Control-Allow-Origin: * header.
The sole purpose of this proxy was to bypass a remote API that didn't do CORS.
