mod_perl is an Apache module that builds the power of the Perl programming language directly into the Apache web server. With mod_perl, CGI scripts run as much as 50 times faster, and you can integrate databases with the server, write Apache modules in Perl, embed Perl code directly into Apache configuration files, and even use Perl in server-side includes. With mod_perl, Apache is not only a web server, it is a complete programming platform.
Getting mod_perl running is easy. Tweaking mod_perl and Apache for the best performance and reliability is much more difficult. This book is about building mod_perl, using it, programming with it, and optimizing it.
