Header tag error in asp.net?
<p>In my application I am getting this error:</p>

<blockquote>
  <p>You can only have one &lt;head runat="server"&gt; control on a page.</p>
  
  <p>Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.</p>
  
  <p>Exception Details: System.Web.HttpException: You can only have one  control on a page.</p>

<p>What could be the problem?</p>
