The Gmail Engine : How they do it!
You've probably noticed that Gmail's interface is extremely fast when compared to other web-based email systems like Yahoo! Mail and Hotmail. This is a result of Gmail's placement of the UI engine on the client-side as a JavaScript module. Whenever you log in to Gmail, a copy of the UI engine is loaded into one of the HTML page frames and remains there for the duration of your session (credit has to be given to Oddpost for being the first ones who perfected this idea). Subsequent actions from the Gmail interface are then routed through the Gmail UI engine in your browser, which in turn makes HTTP requests (via the XmlHttpRequest object) to the Gmail server, interprets the DataPack, and updates the UI dynamically. In contrast, Hotmail and Yahoo! Mail follow traditional web application models and reload the entire UI after almost every action.
I know its rather old, but I just learnt it today and thought I'd share it.
