Microsoft's Active Server Pages (ASP) is the standard technology for creating dynamic Web pages, but ASP alone does not allow Web developers to create scalable Web applications. Microsoft's Component Object Model (COM) is the key that can turn good ASP applications into powerful, multi-tiered, scalable applications that are e-commerce-ready. ASP Internals examines the inner workings of ASP and shows readers how it interfaces with COM, enabling them to develop outstanding Web applications.
Because the source code for ASP is not openly available, author Jon Flanders has created an ASP clone, Active COM Pages (ACP). In revealing its source code, he provides a view under the hood of ASP so developers can finally see and understand how it works and how they can most effectively work with it.
ASP Internals covers each aspect of the ASP runtime. It demonstrates ASP integration with COM+ transactional services. And, most important, it shows readers how COM objects are created and interact with ASP. Other important topics include:
- How ASP is translated to and from the HTTP protocol
- ASP, IIS, and ISAPI, including threads, security, and the Web Application Manager
- Active Scripting, with an explanation of how to add named objects to running scripts
- ASP's IResponse and IRequest interfaces and how they interact with HTTP through ISAPI
- ASP state management at the session and application levels, and related performance issues
- How ASP and the Scripting Engine integrate with COM
- ASP integration with COM+ transactional services
- ASP's built-in internationalization features, including a look atUnicode
Numerous code examples, written in VBScript, demonstrate best practices for performing vital programming tasks.
Written for Web developers who are familiar with ASP and COM, ASP Internals shows readers how to make the best of both technologies in the creation of dynamic, high-quality, database-driven Web applications.
