which type of script would be useful in processing data sent to a server by an ajaxian webpage?
json
another approach used by server-centric web frameworks like the java-based itsnat is to render any hypertext on the server using the same language and templating technology. in this approach, the server knows with precision the dom state on the client, any big or small page update required is generated in the server, and transported by ajax, the exact javascript code to bring the client page to the new state executing dom methods. developers can decide which page states must be crawlable by web spiders for seo and be able to generate the required state at load time generating plain html instead of javascript. in the case of the itsnat framework, this is automatic because itsnat keeps the client dom tree in the server as a java w3c dom tree; rendering of this dom tree in the server generates plain html at load time and javascript dom actions for ajax requests. this duality is very important for seo because developers can build with the same java code and pure html-based templating the desired dom state in server; at page load time, conventional html is generated by itsnat making this dom state seo-compatible. as of version 1.3, itsnat provides a new stateless mode, and the client dom is not kept on the server because, with the stateless mode client, dom state is partially or fully reconstructed on the server when processing any ajax request based on required data sent by the client informing the server of the current dom state; the stateless mode may be also seo-compatible because seo compatibility happens at load time of the initial page unaffected by stateful or stateless modes.

data processing





























data processing is, generally, "the collection and manipulation of items of data to produce meaningful information." 





























in this sense it can be considered a subset of "information processing", "the change (processing) of information in any manner detectable by an observer."
