I rarely use web services, instead preferring to just use GET and POST operations. The XmlHttpRequest object was designed for fetching remote XML, but it's really nothing more than an HttpRequest object, and can be used as such. There's some XML-related stuff, but at the core is just simple HTTP.
If you're doing complex data passing, web services are very helpful, particularly the ability to have multiple typed parameters and complex data that is automatically marshalled/unmarshalled for you, but for simpler stuff, GET and POST are more than adequate. Web services also have a fairly high spin-up cost for parsing the WSDL and making the stubs and stuff. Not a big deal if you have a single page UI that does everything dynamically, but if you're still switching pages and just doing dynamic things within those pages, that cost can be prohibitive. Since GET/POST don't require any of that, they don't have any initialization cost except making an HTTP connection (something browsers are good at), and are therefore ridiculously fast. cheers, barneyb On 8/9/05, S.
