How do I make sure that a website is loaded NOT from cache

My website homepage suupose to look different every time a user loads it. However, it loads from memory thus looks the same every time.

How can i make sure that it loads the new page and not the cached page?

Thanks

protected void Page_Load(object sender, EventArgs e)
{

 Response.Cache.SetCacheability(HttpCacheability.NoCache);
}

in your code behind.

set your request header for caching with Cache-Control: no-cache and response headers as Pragma: no-cache. and expires:

Do you want to that programmatically or not?

Yes - Send HTTP headers that are about cache-control and expires.

No - Press shift before clicking the refresh button...this is to perform a hard reload.
