At Page AND WebControl Level, one can use:

    <%@OutputCache Duration="60" VaryByParam="none" %>


If you want to cache 99% of the page or control, but vary a piece of it -- what they call Donut Caching -- then you may want the Substitution control, which renders a string:


    <callout icon="true" type="class="header">
      <h1>Caching Samples</h1>
      <div class="loginstatus">
        <asp:Substitution ID="Substitution1" runat="server" MethodName="LoginText" /">
      </callout>
    </div>
