"Cross Origin Proxy" is a way how web clients (web browsers) avoid same origin security restrictions. CORS Proxy is a server side software intended resolve client requests to remote services/servers which does not handle CORS requests.

Abstract

This specification describe how cross origin proxy handle client requests.

• Proxy server can be accessed via domain name or ip address with port. For instance : 1.2.3.4:5678
• Proxy server must support http and https.
• Proxy server must handle http and https requests.
• Proxy server v1.0 spec must support at least GET requests.

GET requests

Client request proxy via http(s) with params. Example :

GET https://crossproxy.me/https://requested.site/url?param=value

• https://crossproxy.me/ is an address of the proxy server.
• https://requested.site/url?param=value is a param (remote website url with params)

Proxy server will respond with following headers:

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, HEAD, OPTIONS

Proxy server gets content of requested url and returns this content to the client, with requested Content-Type header.
