What are CGI scripts?
For the absolute newcomer, CGI scripts are programs that run on the web server. They are typically used to run feedback forms, redirection, banner rotation, forums (message boards), counters, search engines, shopping carts, etc. That is, anything that is not simply a straightforward page to be read or viewed is likely to be handled by some sort of script. For these scripts to run, your web host must enable CGI execution on your account – that is they must configure the web server so that CGI scripts installed on your account will actually execute.
Common Gateway Interface (CGI Common Gateway Interface is a web technology that enables clients to request data from a program executed on a web server. When a request is made to a cgi script the server will call the program to be executed and its output is sent to the user to be displayed in their web browser.’); return false”>CGI) is a standard method of transmitting information between an application and a web server. CGI scripts are used to supplement basic HTML HTML is the language used to create web pages. HTML can be created directly using a text editor or a web publishing program such as Microsoft FrontPage or Adobe Dreamweaver ‘); return false”>HTML pages by making your website more interactive and functional. You can program many useful features in CGI scripts, such as hit counters, guest books, order forms and message boards. CGI is an alternative to Microsoft Active Server Pages (ASP Active Server Pages. ASP is Microsoft\’\’s server-side scripting technology. An Active Serv
The difference between your web site just being a virtual billboard and it being an interactive web site, is having the ability to get information to and from your viewers. The Web provides a mechanism for accomplishing this, CGI, the Common Gateway Interface, using CGI scripts. An example of a CGI script would be: Shopping cart systems, hit counters, guestbooks, order forms, mail, maps, etc. CGI scripts are the way most servers communicate with other programs and scripts. CGI scripts are simple text files, lines of code, that are interpreted as requested by the server. A CGI script will work together with other programs and with the HTML content of your web page. Since HTML alone only allows for information to be displayed, CGI scripts give HTML the ability to interact with the visitor. CGI scripts can be written in Perl, PHP, C, Visual Basic, or Python. CGI is not a programming language itself. It’s more of a protocol for communication between the web server and the script. Perl and
CGI (Common Gateway Interface) is a standard for running external programs from a Web server. CGI allows the returned HTML page to be dynamic – for example, with a CGI script you could access information in a database and format the results as part of an HTML page. Not surprisingly, CGI scripts are very popular and used extensively throughout the World Wide Web. There are a number of very good introduction to CGI documents available on the Web. The information given below is a summary of the most important points to remember when using CGI. Please refer to the following for a more in-depth introduction: Intro to CGI – one of the best introductions available. Ada’s Introduction to CGI – a useful introduction. Key points to bear in mind when using CGI scripts: The pre installed scripts available through plesk are the easiest to use, but if a certain script does not do exactly what you want, feel free to look for better scripts on the Web.

CGI scripts are executable programs that are referred to on your Web page but run on the web server. The output of these programs can also be directed to a Web page. For example, let’s say that you wanted to make a guestbook on your Web page, where a form is used for people to fill in data. This data is to be then displayed on a guestbook page. Basically, you will need to create a CGI program that the server executes when somebody fills the form and hits the submit button. This program receives the data, and then displays them on the guestbook page as needed. The CSU Channel Islands directory is an example of a CGI script. A user fills out a Web form and submits the data to a CGI program which queries the directory database and presents the output in HTML format. CGI scripts can be written in a number of programming languages, including VBScript/ASP, PHP, and Perl.
