Problem in clearing browser cache using httpheaders in jsp

[Nizha]

Hi,

The browser cache is not getting clearing inspite of setting these headers..

<%
response.setHea der("Cache-Control","no-cache"); //HTTP 1.1
response.setHea der("Pragma","n o-cache"); //HTTP 1.0
response.setDat eHeader ("Expires",-1); //prevents caching at the proxy server
%>

tried using the HTML metatag even, doesnt seem to work..

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-store">
<meta http-equiv="expires" content="0">

The browser still shows the old version of file but not the new version..

Can anyone pls help me out..
