9. What is CGI?
The Common Gateway Interface or 'CGI' technology is a well established method for web site interactivity. It is not a programming language itself but a standard method to allow external programs to run on a web server. The external programs can be written in many languages, but the most common one is Perl. OUCS recommends the use of 'Safe Perl' to build CGI programs. More information on the Perl language can be found on the Perl web site: http://www.perl.com
