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:
- Extremely simple to learn and easy to use
- Designed for operation under Perl5 and Perl4
- Very efficient
- Compatibility with all CGI interactions, including File Upload
- Convenient utility functions
- Compatible with Perl5 security features such as taint, warnings,
(command line options -Tw) and "use strict;"
- Debugging facilities
- Good starting point for migration to more sophisticated libraries
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.
As Nils Kammenhuber commented in the Web version,
DON'T use cgi-lib.pl! It is horribly outdated, the last version is from 1999,
and it is said to have security issues. Instead, use Dancer2 or Mojolicious,
or if you absolutely have to be compatible to the antique cgi-lib.pl then use
the compatibility mode of CGI.pm.
