I have an ExtJS grid on a web page and I’d like to save some of its state information back to the server when the users leaves the page. Can I do this with an Ajax request onUnload? If not, what’s a better solution?

You can use an Ajax request, but be sure to make it a synchronous request rather than an asychronous one. Alternatively, simply save state whenever the user makes a change, this also protects the data if the user’s browser crashes.
