How to redirect an income http get request with new query parameter

[Shing Hing Man]

Hi,

 I have an endpoint to receive an incoming http request. Then use a processor 
to derive a new value from some query parameters before 

redirecting the request to another URL. Roughly, my code is below. 

from("jetty:http4://localhost:8081/test?matchOnUriPrefix=true").to(redirectProcessor);


In my RedirectProccessor :

public void process(Exchange exchange) throws Exception {
HttpServletResponse response = exchange.getIn().getBody(
HttpServletResponse.class);
String fooValue = (compute fooValue depends on a HttpRequest parameter). 
String url = "http://a.b.com/test?foo="; + fooValue; 
response.sendRedirect(url);
}



I wonder if there is a more elegant way to achieve the above. Something like:


from("jetty:http4://localhost:8081/test?matchOnUriPrefix=true").transform(...).("redirect:http://a.b.c.com/test";);



Thanks in advance for any assistance !
