How To Ensure That the Page is not Cached

Setting Response.Expires to a negative number or 0 disables caching. Sometimes, the use of Response.Expires = -1 doesn’t work because of mismatches between the clocks on the server and the browsers. Be sure to use a large negative number, a little more than a day (1440), to work around those mismatches.

Example:

 Response.Expire = -1441


Here are the commands to place at the top of your ASP scripts, to ensure that the page is not cached:
<%Response.Expires = 60Response.Expiresabsolute = Now() - 1Response.AddHeader "pragma","no-cache"Response.AddHeader "cache-control","private"Response.CacheControl = "no-cache"%>
