You can download CGIProxy from its home page or from BIFSO's site. As described earlier, it has to be installed on a server somewhere outside of the censoring filter; one installation can then be used by many people.
For techies: CGIProxy is a CGI script, or it can be installed under mod_perl for much faster performance if that is available to you. Please install CGIProxy only on a secure server, or else the censors will be able to see what you and your users are doing."
CGIProxy is currently not available for translation in Transifex. We will make an announcement when the project has been set up and is ready to accept translations.
