The reason this does not work is that <%@ include %> is evaluated when the page is
initially compiled, not when the request comes in. The way to dynamically include
different files is to use <jsp:include> with a request time expression for the page
name.

What does getSiteHeader() actually return? If it returns the context-relative URL
of a JSP page (i.e. it ends in ".jsp"), then the JSP page will be executed and the
output it creates will be returned.
