Our website is an AJAX website that makes no page requests after the initial start up of our website. Information is communicated with the server through XMLHttpRequests.
Our website allows users to work online and offline without a connection during a user session. When a connection is detected our website “synchronizes” with the server.
Our problem is that if the internet browser running our website crashes while the user has no internet connection the user cant begin working with our website until she/he gets an internet connection back.
Is it possible to have the browser cache the initial startup page (index.html) along with the other website resources and have the browser use the cached version of the startup page when there is no internet connection present?
(Google)Gears is exactly about this.
