I am not able redirect from the page back to the return URL.
Please Help TIA

string return_url = "";
Url = "https://abc.com/ws/";
Method = "getRates";
Group = "rates";
FormName = "form1";
return_url = "~/app/Public/PaymentTest.aspx?DR={DR}";
NameValueCollection FormFields = new NameValueCollection();
FormFields.Add("username", "xxx");
FormFields.Add("password", "xxxx");
FormFields.Add("pin", "xxxx");
FormFields.Add("dest_country", "Kenya");
FormFields.Add("return_url", return_url);
Response.Write("<html><head>");
Response.Write(string.Format("</head><body onload=\"document.{0}.submit()\">", FormName));
Response.Write(string.Format("<form name=\"{0}\" method=\"{1}\" action=\"{2}\" >", FormName, "post", Url + Group + "/" + Method));
for (int i = 0; i < FormFields.Keys.Count; i++)
{
Response.Write(string.Format("<input name=\"{0}\" type=\"hidden\" value=\"{1}\">", FormFields.Keys[i], FormFields[FormFields.Keys[i]]));
}
Response.Write("</form>");
Response.Write("</body></html>");

Load the return xml into a dataset (note: returnds),and then I retrieve xml respones like this:
int i = 0;
string current = null;
for (i = 0; i <= returnds.Tables(0).Rows.Count - 1; i++) {
if (Information.IsDBNull(returnds.Tables(0).Rows(i)("ValueOfXML")) == true) {
current = "";}
else {
current = Convert.ToString(returnds.Tables(0).Rows(i)("ValueOfXML"));
}
}

You appear to be trying to create an HTML only solution. (That you are using ASP.NET to generate the HTML is a distraction). You will need to write additional javascript on the onload-- you probably don't want to submit the form, that will tell the browser you are done with the page. You would want to make a javascript web service call, the jquery way is easier than the raw XmlHttp
