How do I POST back a specific header

Wombaticus

AM trying to integrate an online payment system, where the secure payment gateway will send a notification to a specified URL on my site - I have given a generic handler (.ashx) address. I can read the data they send (it's a simple POST), but they require that I send back: a notification with a response of: "HTTP/1.1 200 OK". I am not sure what they want... Is a simple

context.Response.ContentType = "text/plain"
context.Response.Write("HTTP/1.1 200 OK")

enough? Perhaps necessarily preceded with

context.Response.StatusCode = 200

? Or is something more sophisticated required, along the lines of

Dim req As System.Net.HttpWebRequest = System.Net.WebRequest.Create("https://secure-gateway-url")
req.Method = "POST"
req.ContentType = "application/x-www-form-urlencoded"
req.Accept = "HTTP/1.1 200 OK"  ?????
req.Headers .Add (   ?????
Dim param As Byte() = context.Request.BinaryRead(HttpContext.Current.Request.ContentLength)
Dim strRequest As String = Encoding.ASCII.GetString(param)
req.ContentLength = strRequest.Length
Dim streamOut As System.IO.StreamWriter = New System.IO.StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII)
streamOut.Write(strRequest)
streamOut.Close()

with what needed at the lines flagged ???? I’d be very grateful for any advice... thanks

I think this post may answer your question, just change the code to 200 http://stackoverflow.com/questions/4495961/how-to-send-a-status-code-500-in-asp-net-and-still-write-to-the-response[^]

Thanks - Google doesn't like me, I've decided :( I did try and Google this myself....

I've written that before years ago, it was just easier for me to find it through search and post a link. Took me a while to find the right one.
