My web application uses the Google APIs Client Library for Javascript https://code.google.com/p/google-api-javascript-client/.
I would like to make the application usable in offline mode as well. It is clear that I cannot make any API calls while the document is in offline mode, but I am wondering what to do with the following step
<script src="https://apis.google.com/js/client.js?onload=handleClientLoad"></script>,
which is the first step in setting up the library. Does this step work in offline mode? And is it safe to cache the client.js file in the applications appcache (that is to include it in its manifest)?
So far, I haven't found any worked-out example for this.
