Building an XSLT Transformation Filter in ASP.NET

Web forms are one way of developing web applications in ASP.NET. Another popular approach is the use of a two-stage XML/XSLT process whereby the executable code in the application generates XML, and then XSLT is used to render that XML into HTML or another markup language. In this article, author Chris Auld demonstrates how to build an ASP.NET HttpModule that supports the use of this style of web architecture. The HttpModule is based around the Microsoft XSLISAPI filter for classic ASP. Along the way, you'll look at several of the newer low-level features of ASP.NET that make it an ideal platform for building advanced web applications that were until recently the territory of complex APIs such as ISAPI.
