how to pass query string object in http.request in nodejs

I already have a request object. Now all i have to do is change the host and make http request again.
//URL type : www.something.com/a/b?w=2&e=2

fun(req,res){

 options = {
   host : <newhost>
   method : req.method
   path : req.path
   headers : req.headers
  }
  http.request(options,...)
}

Now how do i send query string(w=2&e=2) in this option.
I can do it using request module(in nodejs) but that follows redirect(HTTP 302) as well.

Thanks,

http can do this as well

var queryString = 'w=2&e=2';
options = {
   host : <newhost>
   method : req.method
   path : req.path + '?' + queryString // say, var queryString = 'w=2&e=2'  
   headers : req.headers
  }
  http.request(options,...)
