how to redirect a response to a random link?

[nasekt]

if (oSession.oResponse.headers.ExistsAndContains("Content-Type","html")){
oSession.utilDecodeResponse();
var oBodyString = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);
oSession["ui-color"]="yellow";
  var regex = /targetstring/gi ;
if (!oSession.uriContains("google")){
if (regex.test(oBodyString)) {

var request_arr = new Array("www.example.com", "www.bing.com", "www.google.com", "www.ads.com/", "www.time.com", "www.sandbox.com");
var wrl = request_arr[Math.floor(MathObject.random() * request_arr.length)];
oSession["ui-color"]="lavender";
oSession.fullUrl = "https://" + wrl ;

The script says, if the targetstring is present in the response body, then redirect to a random link/URL.

Am I doing it right? Could you  please quide me here?

Thank you.

1. Please stop trying to interpret the response bytes like that. Use oSession.GetResponseBodyAsString() which is both simpler and works properly for non-UTF8 content.

2. Changing the request's URL after it has already returned a response won't do anything. You probably want to instead change oSession.responseCode to 307 and add a new response header oSession.oResponse["Location"] = "https://" + wrl;

That way, the client performs the redirect.
