Hi,
I think that once the response is committed, you can't change the response's header (check the spec).
So, if you set the header after the template is inserted, the change has no effect because the insert commit the response.

Hi everyone,
we are facing a problem with Struts templates (Struts 1.02) and proxy
caching :
The response headers we are setting in jsp files are not being sent back to
the browser whenever a template:insert tag is used :
...
<template:insert template='Template.jsp'>
<template:put name='navigation' content='/navigation.jsp'/>
<template:put name='header' content='/blankHeader.jsp'/>
<template:put name='content' content='/mainMenuContent.jsp'/>
</template:insert>
...
<%
response.addHeader("Cache-Control","no-cache"); response.addHeader("Pragma","no-cache"); response.setDateHeader ("Expires", 0);
response.setHeader("Hello", "hello123");
%>
If we remove the template tags, everything's ok with the headers... (we are
checking the http headers using a local proxy server). We also tried to set
nocache to
'true' in web.xml and/or add the response headers inside the Template.jsp
file,
but neither solved the problem. That's why we assume the templating
mechanism is messing with the headers.
Thanks for your time,
Christof
