What is the use of Cache ?

Session stores things for the specific user,
ViewState for a specific page, as long as you remain in a "postback"
situation (after a redirect, it's gone)
Cache stores things at an application level (*not* user specific). It
can also handle several expiry mechanisms.

There is also Application["A"], also "application" level (as the name
suggests), but without the expiry features of Cache.
