All browsers do not listen to the nocache meta tag, which is what I think you're talking about. Even IE doesn't read that tag properly. So, it may not be worth the effort to add this to struts. Your struts actions classes could add the nocache header to the response before sending which would acheive what you want just not through struts-config.xml.
