CGI
CGI allows you to create pages that will let a user send you information via a fill out form, search a database, and more. CGI is a standard for running programs via a web server. It specifies how the program and the Web must interact, therefore it acts as a Common Gateway Interface between them.
For security reasons, we don't allow users to install CGI scripts on our server. However we have a number of useful scripts already available. They include scripts for receiving input from a form, searching text and more.
