How do I redirect urls in Tomcat like mod_rewrite? You can always use response.redirect("url"), but that exposes the redirection to the client. If you don't want that, use a filter. Here's some sample code for such a filter that redirects based on domain names. import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public final class TestFilter implements Filter { private FilterConfig filterConfig = null; public void init(FilterConfig filterConfig) throws ServletException { this.filterConfig = filterConfig; } public void destroy() { this.filterConfig = null; } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { if (filterConfig == null) return; String sn = request.getServerName(); if (sn.equals("www.domain123.com") || sn.equals("domain123.com")) { HttpServletRequest r1 = (HttpServletRequest) request; // in case you need it. rd = request.getRequestDispatcher("/newdir/index.jsp"); if (rd != null) rd.forward(request, response); } chain.doFilter(request, response); } } |
