cgi-lib.pl - The Standard Library for CGI Scripts

This section describes the de facto standard library, cgi-bin.pl, for Perl CGI scripts. It also provides a tutorial on how to download and install cgi-bin.pl 2.18 to the Apache server on a Windows system.

If you want to develop Web applications with Perl, you should download and use the CGI de facto standard library, cgi-lib.pl developed by Steven E. Brenner.

The cgi-lib.pl library makes CGI scripting in Perl easy enough for anyone to process forms and create dynamic Web content. The library has the following features:

Here is what I did to download and install cgi-lin.pl 2.18:

1. Go to http://cgi-lib.berkeley.edu/.

2. Click the link "Version 2.18" in the "Current versions of cgi-lib available" section. The source code of cgi-lib.pl will be displayed in the browser.

3. Click "File > Save as" from the browser menu. The Save As dialog box shows up.

4. Save the content to C:\local\apache\cgi-bin\ directory and rename it to cgi-bin.pl.

See the next section for testing the cgi-bin.pl installation.
