NOTE
You can write your own code to perform XSL transformations on the
server, or you can use the XSL ISAPI extension to automatically transform
the XML page that includes a reference to the XSL style sheet. Some of
the advantages to using the ISAPI filter are automatic selection and exe-
cution of style sheets on the server, style sheet caching for improved per-
formance, and the option to allow the pass-through of the XML for
client-side processing. To learn more about the XSL ISAPI extension, visit
