In general, the Expires property of the Response object can be used to “expire” the Web page. This prevents a browser or proxy server from caching the page. However, a more reliable way to do it involves sending additional headers with the HTML page:
<%Response.Expires = 0Response.ExpiresAbsolute = Now () - Response.AddHeader "pragma","no-cache"Response.AddHeader "cache-control","private"Response.CacheControl = "no-cache"%> These additional headers will make sure that the browser or proxy server does not cache the page. It will also work on more systems than Response.Expires will by itself.
