I'm integrating CashU Payment gateway.
I need to Post some data using POST method. then I want to redirect to payment gateway site.
I have done so far
 [HttpPost]
public ActionResult Index(string getAmount)
{
// some more process
 var getResponce = ExecutePost(getTokenCode);
}
 private string ExecutePost(string tokenCode)
        {
            var cashuLink = ConfigurationManager.AppSettings["CashULink"].ToString();
            HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(cashuLink);
            var postData = "Transaction_Code="+tokenCode;
            postData += "&test_mode=1";
            var data = Encoding.ASCII.GetBytes(postData);
            webReq.Method = "POST";
            webReq.ContentType = "application/x-www-form-urlencoded";
            webReq.ContentLength = data.Length;
            using (var stream = webReq.GetRequestStream())
            {
                stream.Write(data, 0, data.Length);
            }
            var response = (HttpWebResponse)webReq.GetResponse();
            var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
            return responseString;
        }
My ExecutePost method is returing a Html page string in string formate. But I want to redirect on payment gateway site.
