flush="false" not working?

I was under the impression that Tomcat4 now lets me do JSP 1.2 things
like modify response headers via includes with flush="false". However,
this does not work for me.

I created a very simple test where TEST1.JSP does:

<jsp:include page="/test2.jsp" fluch="false" />

And within test2.jsp I do:

<% response.setDateHeader("Last-Modified",1021852800934L); %>

This *should* set the last-modified header to May 18-ish, but it
doesn't work. If I move the setDateHeader() code to TEST1.JSP, it sets
the header fine... so it seems that even though flush="false" doesn't
throw an error anymore, it still does not allow me to set response
headers as advertised.

Any suggestions or corrections welcome!

I'm using Tomcat 4.0.3 and JDK 1.3.1

The new flush="false" value does *not* change the restriction in the
Servlet spec that included servlets are not allowed to affect headers in
the response.  Therefore, Tomcat will still ignore any attempt to set the
"Last-Modified" header inside an included JSP.

See the relevant Servlet 2.3 and JSP 1.2 specifications for more details.

double check your spelling: in the example you provided you spelled flush
("fluch="false")
