I created a custom router with one endpoint. The custom router looks up the destination of the endpoint based on the URL parameters of the inbound URL. I have an example of this up and running, and I am testing it out in a browser. I am trying to solve one last thing with this. When I make the call in the browser using http://localhost:8787/my-site, the call makes a redirect and the URL in the browser changes to http://server2.xyz.com:8080/my-site. I don t want the user to ever see http://server2.xyz.com:8080/my-site. I want the user to always see http://localhost:8787/my-site. How can I achieve this? I am using Mule 2.2.1 community edition with Java 1.6.

Here is my Mule configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns="http://www.mulesource.org/schema/mule/core/2.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <model name="ProxyService">
        <service name="HttpProxyService">
            <inbound>
                <http:inbound-endpoint address="http://localhost:8787" synchronous="true"/>
            </inbound>
            <outbound>
                <custom-outbound-router class="com.abc.xyz.routing.LookupOutboundRouter">
                    <outbound-endpoint name="custom" address="http://nonexistant.server.com:8080" synchronous="true"/>
                </custom-outbound-router>
            </outbound>
        </service>
    </model>
</mule>

Here is my custom router:

public class LookupOutboundRouter extends AbstractOutboundRouter {
 Logger logger = Logger.getLogger(LookupOutboundRouter.class);

 @Override
 public boolean isMatch(MuleMessage message) throws MessagingException {
  return true;
 }

 @Override
 public MuleMessage route(MuleMessage message, MuleSession session) throws MessagingException {
  String[] urlValues = StringUtils.split(message.getProperty("http.request").toString(), "/");

  String newUri = lookupServiceUri(urlValues[0]) + urlValues[1];
  logger.info("newUri=" + newUri);

  DynamicURIOutboundEndpoint ep;

  try {
   ep = new DynamicURIOutboundEndpoint((OutboundEndpoint) getEndpoints().get(0), new MuleEndpointURI(newUri));

   MuleMessage message2 = send(session, message, ep);

   return message2;
  } catch (EndpointException e1) {
   e1.printStackTrace();
  } catch (MuleException e) {
   e.printStackTrace();
  }

  return null;
 }

 /**
  * This will call the service registry.
  * @param id
  * @return
  */
 private String lookupServiceUri(String id) {
  if(id.equalsIgnoreCase("12345")) {
   return "http://server.xyz.com:8080/";
  } else {
   return "http://server2.xyz.com:8080/";
  }
 }
}
