An origin web server usually never acts as a cache. On any account, the cache
that's closest to client and has a fresh copy of a resource will serve that
resource. In your scenario, any cache hit on the ISA server will prevent
the request from reaching your IIS.

I'm not an ISA expert, but I guess you'll have to configure it in some way
;-)
You must set up your IIS configuration and all web application components
so that all pages, scripts, images etc. are marked with the appropriate Cache-Control
and Expires headers.
