<META> in way you specified damages xhtml organisation of document,
Try following:

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE"/>;

(accent on closing slash).
It is also recomended to use ASP.Net @ OutputCache directive

or something like this:

 <%
        Response.CacheControl = "no-cache";
        Response.AddHeader("pragma", "no-cache");
        Response.AddHeader("cache-control", "no-cache");
  %>
