However on older ones you'll need to use a different technology based on frames as knownow is doing (ref: http://knownow.com ) Other point, in both cases (xmlHttpRequest and frames) you can only communicate with servers on the same domain as the document creating the client's app (in the case of HTML, or XML+XSLT). In order to communicate with servers providing some web services and which are located in other domains, then you'll need to create a "re-director" server located inside your domain.
