title: Dynamically adding attributes to <head> tag ASP.NET
body: <p>How would I go about finding  on my ASPX page (from codebehind) and then adding the attribute "runat=server" to it?
  I have tried using  <code>Page.header.attributes.add(...)</code> and<code>(HtmlHead) Page.FindControl("head");</code> The second one obviously won't work as the Head tag doesnt have an ID.</p>
  
  <p>I can't work out how to change this property and I can't change or add any additional code to the ASPX page - like ID's etc.</p>
