Httpwebrequest to HTTPS brings back the same page!!

[wzb6]

Hi,

I am trying to post form values to a https web page programmatically
using Httpwebrequest but no matter what I do the same login page is
returned instead of the next page. I would very much appreciate if
someone could show me what is it that I am doing wrong. Below is the
code that I am using.

Imports System.IO 
Imports System.Net 
Imports System.Net.Security 
Imports System.Security.Cryptography.X509Certificates 
 
Public Class Form1 
 
    Private Function ValidateCertificate(ByVal sender As Object, ByVal certificate As X509Certificate, ByVal chain As X509Chain, ByVal sslPolicyErrors As SslPolicyErrors) As Boolean 
        If certificate.Issuer.Contains("OU=Diadora") Then 
            Return True 
        Else 
            Return False 
        End If 
    End Function 
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
 
        ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate) 
 
        Dim Req As HttpWebRequest 
        'Dim SourceStream As System.IO.Stream 
        Dim Response As HttpWebResponse 
 
        '-- get file 
        Dim URL2 As String = "https://mysite.com:8443/filelist/library.htm?o_id=2" 
        Req = HttpWebRequest.Create(URL2) 
        Req.Credentials = New NetworkCredential("admin", "password") 
        Req.AllowAutoRedirect = False 
        Response = Req.GetResponse() 
        Dim sr2 As IO.StreamReader = New IO.StreamReader(Req.GetResponse.GetResponseStream) 
        '-- check responser, and make sure you are logged in 
        Dim html_data As String = sr2.ReadToEnd 
        Console.WriteLine(sr2.ReadToEnd) 
        Response.Close() 
 
    End Sub 
 
 
 
End Class

Check out if the framework's default certificate policy works for you. If not, you need to implement your own:
ServicePointManager.CertificatePolicy Property

Hi,

CertificatePolicy is obsoleted for this type, that is why I am using ServerCertificateValidationCallback. But SSL acceptance is not my issue, I am already bypassing this. My problem is that no matter what I do, I never get passed the Log In page.

Have you used a packet watcher to make sure the data you submit via HttpWebRequest is the same as the data you submit via a regular client browser? All cookies, and session header objects in place?

Also, do you not still need to set the HttpWebRequest object to use https? I am pretty sure it ignores it if you don't
