About redirecting after inclusion

[Sergey Karpunichev <ka...@hotmail.com>]

Hi,

Example, shown below works fine with jswdk 1.1 and returns error "Included 
servlet error: 200" with Tomcat 3.1
Error occurs when I try to start with page 1.jsp

Thanks in advance,
Sergey

1.jsp: *************
<html>
<body>
<jsp:include page="2.jsp" flush="true"/>
</body>
</html>

2.jsp: *************
<html>
<body>
<%
do some work here
...
response.sendRedirect("3.jsp");
%>
</body>
</html>

3.jsp: ************
<hr>
TEXT
<hr>

The 'flush="true"' attribute on the <jsp:include> tells Tomcat to commit the
response, which causes (among other things) the HTTP headers to be sent back
to the client.  Once this happens, you can no longer do a sendRedirect()
because that would require modifying the headers.

So, the short answer is you cannot do a sendRedirect() -- or anything else
that implies modifying the HTTP headers, such as trying to add a cookie --
from within an included JSP page.
