Are we changing again?
What is the World Wide Web? The essential characteristics I've used to identify the web are:
Client-Server
Stateless
links -> transition you from page to page.
Browsers now expose DHTML that allows you to modify a page without transitioning to a new page (or even refreshing the page from the server). DHTML is great for building mini calendar widgets and other utilities you would like to use to enrich the user experience. However now companies are starting to integrate DHTML to remove page transitions. EchoSpace claims this makes for a better and faster UI. One of the advantages of the web to me is that I can bookmark any part of a site and return to it. The stateless nature of the web lets me use my bookmarks to jump into the right place in a site. There are cases where this makes no sense. I cannot/should not jump into the payment section of an online airline ticket system. In those cases the server refuses the request since the client doesnt have session information (yeah, that stateless thing was only partly true).
