CGIProxy is, as its name suggests, a CGI proxy software package. A CGI (Common Gateway Interface) proxy appears to a user as a web page that allows the user to access a different site through it, in most cases anonymously. An anonymous CGI Proxy is a type of proxy server that works through an encrypted web form embedded on another web page hosted securely using SSL (Secure Socket Layering), also often called a "Web proxy".CGIProxy is written in the Perl programming language.
