way to extend JSPs or config for no-cache?

[Tom]

Hi,

I would like all my JSPs to have headers attached to prevent them from
being cached. What I want to avoid is having to add:

<%
response.setHeader("Cache-Control","no-store"); // HTTP 1.1
response.setHeader("Pragma","no-cache"); // HTTP 1.0
response.setDateHeader ("Expires", 0); // prevents caching at the proxy
server
%>

to all my pages. Is there a way to override the JSP method that spits out
the HTML code to add these headers, or is there some sort of config file I
can edit? I'm using tomcat 4 with Struts 1.1. I've used the "nocache"
parameter of the controller module and that works great for anything that
Struts spits out, but of course it doesn't affect any JSP pages since tomcat
is handling that.

Thanks,

-Tomas
