Anonymous web proxy works by simply hiding the real IP address of the web proxy user. As soon as a proxy user activates the web proxy, it forwards three extra HTTPS headers to the servers like: HTTP_VIA, HTTP_X_FORWARDED_FOR, and REMOTE_ADDR. These extra HTTPS headers permit targeted servers to figure out that a web proxy is in place. But, your actual IP address is not introduced to targeted servers. If you don’t want targeted servers to find out that you’re using a web proxy service, you can go for elite proxies.
