Hi,

Is there a way to make a page not cache at all? I've tried setting
Duration="0" (in the <%@ OutputCache ......%> directive), but I get the
error "The 'duration' attribute must be set to a positive integer value".
There must be some obvious way to do this that I am overlooking.

Any suggestions will be greatly appreciated.

Thanks,
Michael Bunger

I think there may be confusion as to WHICH cache you are talking about. Are you talking about the BROWSER's cache, or the ASP.NET cache on the server? Any page with no cache directive will NOT be cached by ASP.NET.

However, the user's local browser may well cache the page (which is a totally different process). If the user's browser cache is hte issue, you can try:

Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache"
Response.Expires = -1
