Sorry. The cache is where the browser keeps its list of recently accessed web pages, along with a copy the pages' contents. what is supposed to happen is that when you access a page that it already in the cache, the browser goes to the site and asks if the contents of the page has changed since it was last accessed. If not it displays the saved version rather than download the page.
Sometimes browsers get upset and this does not work as advertised. So if you are having trouble with a site, the first thing you should do is to clear out the browser cache. This is done through a browser menu option; although I believe that Windows can also achieve this through the control panel. As I don't use Windows or Internet Explorer, I am afraid I can't help you further. On Firefox, the cache is cleared by "Tools->Clear Recent History", so there should be a similar option on IE.
