Port Redirect

[lumavanossi]

Hi,

 What's the better way to redirect http://localhost/search to 
http://localhost:8080 and also http://localhost/search?query=XXX to 
http://localhost:8080/search.jsp?query=XXX .
 Maybe like Google does with google.com/search?q=mercado1 .
 Mod Rewirte ProxyRequests ?
 How to do that?
 Including security issues.

Thanks!
