"Redirection" after "dsp:include" wont work in ATG.

Normally in J2EE, we can redirect to another page after  any "include" in the page.

For example this will work

<@include page="test2.jsp"/>
  <jsp:forward page="test3.jsp"/>

or

<jsp:include page="test2.jsp"/>
<jsp:forward page="test3.jsp"/>

But once you have dsp:include in page, you will not be able to redirect to any other page using any redirection operation like "Redirect" droplet or "jsp:forward" or request dispatcher etc.

For example:
test1.jsp

<%@ taglib uri="dsp" prefix="dsp"%>
<dsp:page>
   I am in test1.jsp <br>

  <%-- including test2.jsp --%>
  <dsp:include page="test2.jsp"/>
 
  <%-- redirect to page test3.jsp --%>
  <dsp:droplet name="/atg/dynamo/droplet/Redirect">
    <dsp:param name="url" value="test3.jsp"/>
  </dsp:droplet>

  end of test1.jsp <br>
</dsp:page>

test2.jsp

<%@ taglib uri="dsp" prefix="dsp"%>
<dsp:page>
 I am in test2.jsp <br>
</dsp:page>

test3.jsp

<%@ taglib uri="dsp" prefix="dsp"%>
<dsp:page>
  I am in test3.jsp <br>
</dsp:page>

if you access http://localhost:8080/test1.jsp
output -

I am in test1.jsp
I am in test2.jsp
end of test1.jsp

 If you remove " <dsp:include page="test2.jsp"/>" in test1.jsp and
access http://localhost:8080/test1.jsp
you will be redirected to test3.jsp

I am in test3.jsp

If you use jsp:include or @include instead of dsp:include like below

  <jsp:include page="test2.jsp"/>
  <dsp:droplet name="/atg/dynamo/droplet/Redirect">
    <dsp:param name="url" value="test3.jsp"/>
  </dsp:droplet>

You will be redirected to test3.jsp.
