A extended thinking from Atlas

today when I study Atlas , suddenly a thinking pop up , since atlas is used for user can retrieve data from client side directly , could we do the whole web page work like this ?
what I mean is we can retrieve the html part also by client script , so we can seperate the page into several parts , every part html can be retrieved independaly , and also the data part still retrive as Ajax doing now . so we can unify our page working style , we can retrive the whole html page framework , or retrieve one or more parts of the html page at a time , and also can retrive any data part of the page . As a result the whole web application always hold a unique url which is this app 's domain , and the url in address will not changed , what we request the web page is done in the page by client side operation , and just comminucate with web server what we need , either html markups or xml datas .

what do you think of this ? of course this is just a suddenly idea , without any deeply thinking and detail realization .

Wouldnt that be what frames provide?
Yes, this is possible ... and is often called the "single page application" model, that is becoming a viable option with AJAX techniques. You'll want to be careful about user model though, and there are some places where regular link navigation is still useful (eg. to be able to bookmark specific content).
