There's no guarantee that a browser applies caching or expiration
instructions to locally stored pages. Still, for most browsers this
does work.

Either set the OutputCache directive on your page(s)

<%@ OutputCache Location="None" %>

or set the Cache property of the HttpResponse in your code-behind class:

Response.Cache.SetCacheability(HttpCacheability.NoCache);

(which is equivalent to the directive shown above)
