[2005] HttpWebRequest not sending cookies

[Bug]

So, i figure after a week of exhausting every possible stupid reason for this, somehow when i send a HttpWebRequest with cookies attached the site either doesnt get the cookies or doesnt accept them.. the server is Apache Tomcat 6.0 if that matters.. and also i set up a test using an old ASP page i had, and i know it works on other pages, yet on this server it doesnt hold or use the cookies..

heres my code too:

Private CookieCont As New CookieContainer

Private Function GetWebData(ByVal strURL As String) As String
  objWebRequest = HttpWebRequest.Create(strURL)
  With objWebRequest
    .CookieContainer() = CookieCont
    .UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1"
    .Timeout = 4000
    Dim strOutput As String = New StreamReader(.GetResponse().GetResponseStream()).ReadToEnd
  End With
  GetWebData = strOutput
End Function


Private Function PostWebData(ByVal strURL As String, ByVal strPostData As String) As String
  objWebRequest = HttpWebRequest.Create(strURL)
  Dim ToSend As Byte() = System.Text.Encoding.ASCII.GetBytes(strPostData)
  With objWebRequest
    .Method = "POST"
    .UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1"
    .ContentType = "application/x-www-form-urlencoded"
    .CookieContainer() = CookieCont
    .Timeout = 4000
    Dim objSendtoServer As Stream = .GetRequestStream
    objSendtoServer.Write(ToSend, 0, ToSend.Length)
    objSendtoServer.Close()
    Dim strOutput As String = New StreamReader(.GetResponse().GetResponseStream()).ReadToEnd
  End With
  PostWebData = strOutput
End Function

so basicly, when i log in using the PostWebData function, and then use the GetWebData function to get the next page, no cookies go with it and the server think's i've logged out.. i've put in code to count and look at the cookies and it seams, even if i manually add them they still dont exist for some reason..

i thought it may have also been the URL, because the site is on a different port alike: http://example.blah.com:8080/login (and no i cant just use: http://example.blah.com/login) cause the port is the only way in

So does anyone have any idea, cause i am truely stumped
