This plugin will not put your entire WordPress website behind a proxy! It will allow you to use your server as a proxy server. By using links in this format: YOUR_SERVER_URL?zapp_url=PROXIED_URL – the PROXIED_URL will see your IP address as your server’s IP address, even if you are seeing the web page from PROXIED_URL
