I want to implement the header as like twitter has. I have observed couple of things like when i click on home link, the url has changed but still page header is not loaded and the content of the page is changed. Can anybody give me some suggestion so that i can put that design on my site?
UPDATE
I am wondering that how twitter manages offline site. Because I have tried couple of example for application caching, and i have got warning on my firefox browser about page storing. While I am opening twitter site on firefox this warning dosen’t appear. What could be the reason. I have also observe that twitter is using locaStorage first time. What is the concept behind twitter offline site caching?
As Cyberfox already mentioned – it’s called browser state. The JS-framework BackboneJS implements this method for you: http://documentcloud.github.com/backbone/.
