How to set up forwarding between wild-fly 8 domains?

Question

Java

There are two domains
- domain1.com
- domain2.com
Both point to the same wildfly-8 server address.
Is it possible to set up redirection by wildfly itself so that when going to domain1.com, the user is redirected to domain2.com?
Examples and useful links are welcome.

Answer 1

This is much easier to do with nginx or apache (or whatever you use to proxy requests to wildfly). Well, if you are too lazy to mess with them, then you can use such a filter in a web application:

public class HostFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        HttpServletResponse httpServletResponse = (HttpServletResponse) response;
        String host = httpServletRequest.getHeader("Host");

        if ("domain1.com".equalsIgnoreCase(host)) {
            httpServletResponse.sendRedirect("https://domain2.com" + httpServletRequest.getRequestURI() + "?" + httpServletRequest.getQueryString());
            return;
        }

        chain.doFilter(request, response);
    }
}
