Javascript to preload a swf file?

Is it possible to use a Javascript preloader to cache a swf file? I have a rather sizable .swf file on page #2 of a site and wanted to know if I could start preloading it when people are reading page #1? I am also wondering if flash needs to load in a certain way in order for a preloader inside that flash file to work properly… Thanks in advance…

I found this swf preloader:

but I don`t know how to use it :confused:

This will help you to preload SWF from JavaScript:
