    Description:  Apache is the most popular web server on the Internet because it is free, reliable, and extensible. The availability of the source code and the modular design of Apache makes it possible to extend web server functionality through the Apache API.
    For the most part, however, the Apache API has only been available to C programmers, and requires rebuilding the Apache server from source. mod_perl, the popular Apache module used primarily for enhanced CGI performance, changed all that by making the Apache API available to Perl programmers. With mod_perl, it becomes simple to develop Apache modules with Perl and install them without having to rebuild the web server.
    Writing Apache Modules with Perl and C shows how to extend web server capabilities regardless of whether the programming language is Perl or C. The book explains the design of Apache, mod_perl, and the Apache API. It then demonstrates how to use them to perform for tasks like the following:

    Rewriting CGI scripts as Apache modules to vastly improve performance
    Server-side filtering of HTML documents, to embed special markup or code (much like SSI)
    Enhancing server log functionality
    Converting file formats on the fly
    Implementing dynamic navigation bars
    Incorporating database access into CGI scripts
    Customizing access control and authorization to block robots or to use an external database for passwords
    The authors are Lincoln Stein and Doug MacEachern. Lincoln is the successful author of How to Set Up and Maintain a World Wide web Site and the developer of the widely used Perl CGI.pm module. Doug is a consultant and the creator of the innovative mod_perl Apache module.

    Description:  Writing Perl Modules for CPAN offers Perl developers a comprehensive guide to using and contributing to the Comprehensive Perl Archive Network (CPAN). Starting with a general overview of CPAN's history, network topology, and navigational mechanisms, the book quickly brings you up-to-speed regarding how to search out and install available modules. However, in the true open source spirit, author and experienced Perl developer Sam Tregar teaches you how to not only use, but also contribute to CPAN via an in-depth discussion of module creation, submission, and maintenance.

    Beginning with a survey of basic design principles, Tregar takes care to discuss all issues relevant to developers wishing to create great Perl modules, including choosing a proper name, properly using Perl's POD (plain old documentation) feature, concepts surrounding functional and object-oriented API development, and much more. Tregar then proceeds with a complete dissertation of how modules should conform to CPAN module specifications, covering required distribution files and coding considerations, in addition to offering advice regarding proper module testing. After demonstrating how to create a module and prepare it for release, Tregar guides you through the CPAN module submission process and discusses module maintenance once the module has been contributed to the CPAN service.

    Description:  On the World Wide Web, people are accustomed to using graphical browsers such as Netscape Navigator or Mosaic as their only interface for visiting remote sites, accessing up-to-date documents, and filling out forms. But graphical browsers can be limiting: the very interactivity that makes them so intuitive to use also makes them clumsy for automating tasks. If you want to get the latest weather report every few hours, track a Federal Express package online, or use a dictionary server repeatedly throughout the day, using your browser to perform the same task over and over can become cumbersome. As with any repetitive task, these applications are best done by writing a script.
    Web Client Programming with Perl shows you how to extend scripting skills to the Web. This book teaches you the basics of how browsers communicate with servers and how to write your own customized Web clients to automate common tasks. It is intended for those who are motivated to develop software that offers a more flexible and dynamic response than a standard Web browser.

    Using this book, you'll learn how to:
    Automate repetitive queries on the Web
    Detect broken hyperlinks on your site
    Write simple "robots" that traverse hyperlinks across a site, and across the Web in general

    This book will be of interest to:
    Web administrators who need to automate repetitive tasks or reduce maintenance time
    UNIX shell programmers who want to interface their scripts to the Web
    Commercial software developers and consultants who need reference material for technical Web specifications and proof-of-concept examples
    Most of the examples in this book use Perl, a versatile and portable language that is already familiar to many CGI programmers and UNIX power users. The book does not teach Perl, but the techniques used in the book should be easily followed by anyone with some programming background and can be adapted to whatever language you choose.

    Description:  Perl, one of the world’s most diffuse programming languages, was born out of the need to resolve the creator's dissatisfaction with what were at the time standard data-parsing solutions. Indeed, since the 1.0 release in 1987, Perl has been heralded for its powerful parsing capabilities features that are further enhanced through the thousands of Perl extensions made available through CPAN (the Comprehensive Perl Archive Network).

    Pro Perl Parsing begins with several chapters devoted to key parsing principles, discussing topics pertinent to regular expressions, parsing grammars, and parsing techniques. This material sets the stage for later chapters, which introduce numerous and powerful CPAN parsing modules, and provide an ample supply of example applications.
