Just found out that there’s a name for the type of apps that we’ve been working on for the last couple of years. It even has a catchy acronym.
Those are actually Single Page Applications, or SPAs. There’s even a Wikipedia entry describing the 10 year history of SPAs.
The only good thing is that the page mentions thin server architecture, which is a big win, and probably the only thing that makes sense – the rest is just somebody misspelling AJAX driven web app.
