Creating absolute urls in CQ for consuming externally.

1) Selector which gets parsys

    StringWriter defaultHtml = new StringWriter();

    pageContext.pushBody(defaultHtml);

  %>

    <cq:include path="<%=nodeName%>" resourceType="<%=resourceType%>"/>

  <% pageContext.popBody();%>

<%=defaultHtml %>

2) the above produces relative urls, so the externall app wont show images, styles, any scripts.

3) how can make the above output with absolute urls. Please suggest.
