ASP implementation waits a few seconds to automatically return the page effect

My requirements: After the update and other operations, after the prompt page, delayed 2 seconds, back to the original operation of the page (updated) Focus on the prompt page "OK." ASP ". The interface is as follows

Program:

Program code
......
<%
Dim come
Come=request.querystring ("Come")
%>
<meta Http-equiv=refresh content= ' 2; Url=<%=come%> ' >
<title> Background Management </title>
<style type= "Text/css" >
......

The action page response after the operation completes. Redirect "ok.asp?come= Action page"

If just want to load the page is the most recent page reread, you can use the cache to prevent the page to achieve, the page as long as the open must update the data, rather than keep the original data unchanged, equivalent to a refresh.

--The following disable caching module is added at the beginning of the page--

<%
Response.CacheControl = "No-cache"
Response.AddHeader "Pragma", "No-cache"
%>
