Application caching in the browser?

[Audrey A Lee]

Hello people,

Are any of you implementing application caching in the browser?

Here is the use-case I am interested in:

End-user-Bob uses his browser to navigate to
the_bob_end_user_crm_app.com

While there he navigates to these URLs:

the_bob_end_user_crm_app.com/accts/show/123
the_bob_end_user_crm_app.com/accts/show/321
the_bob_end_user_crm_app.com/accts/show/45678

Each of the above URLs displays dynamic HTML from an app-server.

Next, he disconnects his browser from the web.

He navigates to this URL:

the_bob_end_user_crm_app.com/accts/show/87654

He receives a message:

You are not connected to the net.
the_bob_end_user_crm_app.com/accts/show/87654
is unavailable.

He navigates to this URL:

the_bob_end_user_crm_app.com/accts/show/123

He sees HTML which is cached in his browser via "application caching"

Are any of you doing anything like this?

I know it is possible because gmail.com exhibits this type of
behavior.

I'm looking for demos/tutorials/discussions which would teach me how
to do this.

Thanks,

Audrey
