  cg-eye has three components:
• cg-eye offline - A test harness to simulate a CGI environment offline, without the need for a browser or HTTP server. See also Tom Christiansen's Idiot's Guide.
• cg-eye interactive - An online harness to specify an HTTP request to send to your server and print diagnostics on the server's response. See also brian d foy's httpeek.
• cg-eye live - An online harness to intercept a request from a browser (normally generated "live" from an HTML form) and forward it to your server. Details of both the Request and the server's Response are printed. See also Nick Kew's Header Dumper.
• A test suite for HTTP and CGI development - cg-eye is a test harness for HTTP and CGI. It may be used as an intermediate stage between running your software from the commandline and putting it online, and will diagnose a number of potential problems.

The article introduces some of Perl's object-oriented concepts and syntax. The article also discusses Lincoln Stein's CGI class which you can use off-the-shelf to rapidly develop robust CGI scripts. The article concludes by extending Mr. Stein's CGI class to develop a small template engine used in processing a multi-page form.
• Welcome to CGI for the Total Non-Programmer. (Cool) - This tutorial will walk you through the basics of creating CGIs with Perl on a Unix platform. Unlike other tutorials I've read, this does not assume you know anything about CGIs, Perl, or Unix.
• The following set of examples has been used by Tom and Tom's trainers in some of their Perl training courses.Many will find their way into the Perl Cookbook that should be out late this spring, so are necessarily copyrighted by Tom unless otherwise attributed.

• Datapult/PF   is a tool for generating dynamic HTML documents. Without writing a custom CGI program, user input forms can be created and processed, pages can automatically react to the capabilities of the web browser, and information sources such as SQL databases or user-written modules can be tapped to generate content.

Security:

• sbox is a CGI wrapper script that allows Web site hosting services to safely grant CGI authoring privileges to untrusted clients. In addition to changing the process privileges of client scripts to match their owners, it goes beyond other wrappers by placing configurable ceilings on script resource usage, avoiding unintentional (as well as intentional) denial of service attacks. It also optionally allows the Webmaster to place client's CGI scripts in a chroot'ed shell restricted to the author's home directories.
