how to transfer and post data to a url at the same time??

[ioloop]

Hi all

I am trying to insert an order into my own database, post some data to a third party payment system and redirect the user to payment page all in the same method.

I can write to the database ok, i can post the data to the payment URL but i cant redirect the user.

I have tried Server.TransferRequest but im getting a PlatformNotSupported exception. I have also tried using a basic html form (which works) but doesnt allow me to execute of code in the .cs file (to insert into the database).

I have this on the button click event:

 
protected void Btn_Purchase(object sender, EventArgs e)
    {
        Order o = (Order)Session["order"];
        Customer c = (Customer)Session["customer"];
        onlinepayments.OrderDAC.InsertOrder(o, c);
 
NameValueCollection nv = new NameValueCollection(3);
        nv.Add("epdqdata", encryptedData);
        nv.Add("returnurl", "http://www.mysite.com");
        nv.Add("merchantdisplayname", "MySite");
 
        Server.TransferRequest("https://secure2.epdq.co.uk/cgi-bin/CcxBarclaysEpdqEncTool.e", true, "POST", nv);

any suggestions are much appreciated...

thanks

Server.TransferRequest will only work with IIS 7. Are you attempting to transfer to a page outside your application or server? Then you are using the wrong functionality as this is simply meant to transfer a request and context to another part of an IIS 7 application.
