The Apache HTTP server (simply "Apache") powers most of the sites on the World Wide Web. Programmable, extensible, and highly-configurable, the Apache web server provides for uploads, downloads, CGI and other server-side scripting, and web site security.

Pro Apache, Third Edition is a new revision of Peter Wainwright’s bestselling book on Apache configuration and administration. In addition to installation, maintenance, and deployment, the book demonstrates how to configure Apache to use Perl, PHP, and Python as server-side scripting languages. And unlike other books on Apache, Pro Apache provides comprehensive information on both major revisions - 1.3 and 2.0 - of the software.
