Here is a quick smattering to do what you want; this is the dofilter for
the cclass you'll write that extends filter. You'll want to append
stuff at the end... play with it a little and you'll get the idea pretty
quick. You can alter anything in the body.. but for your case, just
add your meta tag to the end.
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse)
response;
CharResponseWrapper wrapper = new
CharResponseWrapper((HttpServletResponse)response);
chain.doFilter(request, wrapper);
CharArrayWriter caw = new CharArrayWriter();
String body =
wrapper.toString();
StringBuffer newBody = new
StringBuffer();
caw.write(newBody.toString());
response.setContentLength(caw.toString().length());
response.getWriter().write(caw.toString());
response.getWriter().close();
}

Well that was my thought as well, just wasn't sure how to go about that.
Any hints?
Thanks

Or use a filter to append that <meta> tag onto any response that is
html...

Hmm... Isn't this a job for JSP. Rename your index.html to index.jsp
and add a new first line of:
<%@ page language="java" %>
Then insert this into the point you want the page output to change:
<meta name="agmips"value="<%=request.getServerName()%>">
Best of luck,
