    Hai guys,

    I create a windows application using vb.net and put the httpwebrequest in the timer which is have a function for checking a time.

    For the first request its working fine but when it continue to the second request I got an error The remote server returned an error: (400) Bad Request.

    I already close GetResponseStream, dataStream and reader. I also used keepAlive = False

    The request server is using HTTP version 1.0.

    Dim request As HttpWebRequest = CType(HttpWebRequest.Create(URLStr), HttpWebRequest)
Using response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
    Dim dataStream As Stream = response.GetResponseStream()
    Dim reader As New StreamReader(dataStream)
    Dim MTstatus As String = reader.ReadToEnd()

    If status = "100" Then
       status = "Ok"
    End If

   reader.Close()
   response.Close()
   dataStream.Close()
End Using

    If Not (IsPostBack) Then
    Try
        Dim fr As System.Net.HttpWebRequest
        Dim targetURI As New Uri("http://weblogs.asp.net/farazshahkhan")
 
        fr = DirectCast(System.Net.HttpWebRequest.Create(targetURI), System.Net.HttpWebRequest)
        'In the above code http://weblogs.asp.net/farazshahkhan is used as an example
        'it can be a different domain with a different filename and extension
        If (fr.GetResponse().ContentLength > 0) Then
            Dim str As New System.IO.StreamReader(fr.GetResponse().GetResponseStream())
            Response.Write(str.ReadToEnd())
            str.Close() 
        End If
 
    Catch ex As System.Net.WebException
        Response.Write("File does not exist.")
    End Try
End If
