CGI Form

In order to interact dynamically with the web server, the users exercise the technique called CGI form.  The pages having coding in HTML and containing a form would be using the CGI program so as to processing the form’s data soonest its submittal by the users. For instance, when the internet user visits the web site with a view to find for certain information on the specific topic and happens to find the link on that site offering the newsletters via e-mail. Thus prior to receiving that particular newsletter he would be required to fill up the CGI form. Here the user will be providing details of the relevant particulars of himself. Then this filled form will be sent to the server via CGI program. The server will process this information in order to enlist that particular user in its database prior to initiating the newsletter service for that user.
