Abstract: Various embodiments enable installable applications that are to be used on a local client machine to utilize an application cache manifest file that resides remotely, on the web, to define various resources that are to be updated and available offline after the installable application has been deployed on the local client machine Whenever the content of the manifest file is updated on the web, the installed application automatically updates its local application cache resources and allows the installed application to use those resources offline. This is done without having to install a new update of the application or burden the user with having to navigate to a location to obtain the updated content.
