Howdy,
Why do this in a valve (tomcat-specific) when you can do it in a Filter in a
container-independent way?
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
throws IOException, ServletException {
if(req instanceof HttpServletRequest) {
HttpServletRequest hreq = (HttpServletRequest) req;
hreq.addHeader("test-id", "test-value");
}
chain.doFilter(req, res);
}
That's all you would have to do.
