Hi chaps

In order to improve the perceived loading times of my application page, I want to do a couple of things ...

1. Have the browser pre-cache as much content as possible using a hidden frame on the login page. The idea is while the user is entering his credentials, some of the page content, eg prototype and JS libraries are downloaded in background

2. Have the main page quickly display a "loading..." animation while the remaining content is downloading.

Does anybody have any recipes for this?

many thanks
