Q: What is an anonymous proxy?
A:
Anonymous proxy servers hide your IP address and thereby prevent unauthorized access to your computer through the Internet. Webmasters will be unable to track you and do not know that you are surfing through a proxy server. In addition, anonymous proxy hides your IP address and effectively hides any information about you and your reading interests. In some database systems which make use of the latest algorithm, you are able to find the most modern lists, as the proxies are checked every minute, and the list is updated daily from various sources.

    end if
%>

PHP without Proxy detection

<?
    $ipaddress = getenv(REMOTE_ADDR);
?>

PHP with Proxy detection

<?
    if (getenv(HTTP_X_FORWARDED_FOR)) {

    }
?>

JSP without Proxy detection

<%
    String ipaddress = request.getRemoteAddr();
%>

JSP with Proxy detection

<%
    if (request.getHeader("HTTP_X_FORWARDED_FOR") == null) {

    }
%>
