    HttpWebRequest

    A little about what I am trying to accomplish

    I am tyring to do a HttpWebRequest to a company called Paymentech.

    Here are some of there requirements:
    It supports one method of communication - HTTPS
    I will only be doing HTTP POST requests.
    The web address are as follows.
    orbitalvar1.pay mentech.net/authorize on port 443
    Now the XML gateway URL must be accessed using the https protocol. But
    interfacing to the Orbital Gateway using SSL does not require us to have a
    certificate. The Orbital Gateway uses a non-authenticated SSL session,
    meaning the client is not authenticated using a digital certificate as a
    component of the SSL negotiation.
    The Orbital Gateway uses source IP authentication to authenticate the
    request generation. This is only true for the production system, the
    development system will not need this.

    This is the code I have to try to send the xml:
    Dim xmlDoc As New XmlDocument
    xmlDoc.Load("C: \CreditCardAuth .xml")
    Dim request As HttpWebRequest =
    CType(HttpWebRe quest.Create("h ttps://orbitalvar1.pay mentech.net:443/authorize"),
    HttpWebRequest)
    request.Method = "POST"
    Dim requestData As Byte() =
    System.Text.Enc oding.UTF8.GetB ytes(xmlDoc.Out erXml)
    request.Content Length = xmlDoc.OuterXml .Length
    Dim requestStream As Stream = request.GetRequ estStream
    requestStream.W rite(requestDat a, 0, requestData.Len gth)
    requestStream.F lush()
    requestStream.C lose()
    Dim response As HttpWebResponse = CType(request.G etResponse,
    HttpWebResponse ) Dim responseData As StreamReader = New
    StreamReader(re sponse.GetRespo nseStream)
    Dim sendData As Byte() = System.Text.Enc oding.UTF8.GetB ytes(xmlDoc.Out erXml)

    I am getting this error on the requestStream
    The underlying connection was closed: Unable to connect to the remote
    server.
    TIA,
    Brett
