It sounds like what you need for your use case is for some set of
resources to be immediately available when gmail starts. This set of
resources is a mixture of "static" resources like JS files (and
presumably HTML files), and "dynamic" resources like the list of
An alternative solution would be to tell the browser what resources
you need, and how to download them (to allow for incremental downloads
of just new emails for example). Then the browser can download these
resources as it sees fit. On a mobile device this could happen even if
the browser is not running, similar to the iPhone push mechanism.
This should be significantly easier to secure since you don't allow
the full power of the web platform to run in the background.
I would think that this can be done using extensions to the AppCache feature.
