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 ...

Windows NT File System Internals presents the details of the NT I/O Manager, the Cache Manager, and the Memory Manager from the perspective of a software developer writing a file system driver or implementing a kernel-mode filter driver. The book provides numerous code examples included on diskette, as well as the source for a complete, usable filter driver.This book appeals to a wide audience: system programmers implementing kernel-mode code such as file systems, device drivers, network redirectors, or filter drivers; system administrators who simply want to learn more about the systems they manage; software engineers interested in NT internals; and computer science students examining the intricacies of file system technology.Topics covered in the b...

Web apps would run much better if heavy calculations could be performed in the background, rather than compete with the user interface. With this book, you'll learn how to use Web Workers to run computationally intensive JavaScript code in a thread parallel to the UI. Yes, multi-threaded programing is complicated, but Web Workers provide a simple API that helps you be productive without the complex algorithms.If you have an intermediate to advanced understanding of JavaScript especially event handling and callbacksyou're ready to tackle Web Workers with the tools in this example-driven guide.Start creating Web Workers and understand what they can and can't do Determine which browser versions support the API Use dedicated Web Workers for tasks that co...

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 ...
