This article describes how to create and process simple web input forms. No other special tools are required. They are not repeated here.
As you start to program more advanced CGI applications, you'll want to store data so you can use it later. Maybe you have a guestbook program and want to keep a log of the names and email addresses of visitors, or a page counter that must update a counter file, or a program that scans a flat-file database and draws info from it to generate a page. Most web servers run with very limited permissions; this protects the server and the system it's running on from malicious attacks by users or web visitors.
All I want to do it is read some form data.!! I'm not a perl programmer so this is doing my head in. I also want to be able to access all the items submitted in a form.
I have 2 Macs and have added Firefox v 9. I get a message asking what application do I want to open the file. I've tried all applications to no avail All other functions on the banking site can be used with out problem.

The Common Gateway Interface, or CGI, is a set of standards that define how information is exchanged between the web server and a custom script. To understand the concept of CGI, let us see what happens when we click a hyper link to browse a particular web page or URL. Web Server parses the URL and looks for the filename.
This is an introduction to writing CGI programs in the C language. The principles are illustrated with very simple examples. Typically, there are simple server-side scripts available for simple, common ways of processing form submissions, such as sending the data in text format by E-mail to a specified address.
This module is intended to take care of the different cases and provide a simpler interface to the Python script. It also provides a number of utilities that help in debugging scripts, and the latest addition is support for file uploads from a form if your browser supports it. The output of a CGI script should consist of two sections, separated by a blank line.
