Deprecated. obsolete; all functionality moved up to DocPage and CachedPage as appropriate

public class ClientsideXslSensitivePage

extends CachedPage

The design of the domutil package has been largely predicated on the belief that XSL trasnformation had to be done server side. That made sense in 2000, when clients able to do XSL transforms client side were rare as hen's teeth. Increasingly, however, we can expect that most clients are XSL-capable, and it makes sense for a whole lot of reasons to offload XSL processing to client side. This servlet checks whether the client claims to be able to handle XML, and if so hands off the XSL processing to the client. See http://www.w3.org/TR/xml-stylesheet/
