Notice which values show information about your server and CGI program, and which ones give away information about you (such as your browser type, computer operating system, and IP address). 29 Chapter Three CGI Environment Variables Let’s look at several ways to use some of this data. Referring Page When you click on a hyperlink on a web page, you’re being referred to another page. The web server for the receiving page keeps track of the referring page, and you can access the URL for that page via the HTTP_REFERER environment variable.

All of these things require some more advanced processing of the form data, and that will usually involve using control structures in your Perl code. Control structures include conditional statements, such as if/elsif/else blocks, as well as loops like foreach, for and while. If Conditions You’ve already seen if/elsif in action. The structure is always started by the word if, followed by a condition to be evaluated, then a pair of braces indicating the beginning and end of the code to be executed if the condition is true.

You should see all of your form field names and the data you typed in as part of the URL. This is one reason why GET is not the best method for handling forms; it isn’t secure. GET is NOT Secure GET is not a secure method of sending data. Don’t use it for forms that send password info, credit card data or other sensitive information. Since the data is passed through as part of the URL, it’ll show up in the web server’s logfile (complete with all the data). Server logfiles are often readable by other users on the system.
