setting cache-control header

Question

I have to set cache-control header to "no-cache, no-store".For this i am using html meta tag

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate"/>
<meta http-equiv="Pragma" content="no-cache"/>
<meta http-equiv="Expires" content="0"/>

in the tag of the web page. I inspected in firebug. In spite of having cache-control to desired one it is having as "private". I am using ASP.NET framework. Any idea why this is failing?

Do you mean the HTTP headers when you say "header section of the web page"? — Oded

from code behind you add:

 Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetNoStore();

I specifically had a problem where in IE (only) the content of Colorbox iframes was being cached under the private setting and this cleared up the problem. Thanks!
