Is there a way to clear a user's browser of my page, or say not to use cache?

Question

Is there a command in classic ASP I can use to tell the browser not to pull the page from it's cache, or, to not cache, or clear the cache of my page?

Answer 1

You can use HTML meta tags:

<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="Fri, 01 Jan 1999 1:00:00 GMT" />
<meta http-equiv="Last-Modified" content="0" />
<meta http-equiv="Cache-Control" content="no-cache, must-revalidate" />

Or you can use ASP response headers:

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

Answer 2

Not asp related, this is a HTTP question. You do it by modifying some aspect of http caching like Cache-Control, etag, Expires etc. Read RFC2616 especially Caching in HTTP and set the appropriate header.
