Maybe something like this.
Dim http As HttpWebRequest = CType(WebRequest.Create("http://www.nerldc.org/Default.aspx", HttpWebRequest)
http.Timeout = 10000 ' 10 secs
http.UserAgent = "NERLDC"
Dim hwr As HttpWebResponse = CType(http.GetResponse, HttpWebResponse)
Dim enc As Encoding = Encoding.GetEncoding(1252)
Dim rdr as StreamReader = New StreamReader(hwr.GetResponseStream, enc)
Do
Dim line As String = rdr.ReadLine
If line IsNot Nothing Then
'Do what you need to do
'if it's a csv file, use the line below
'Dim s() As String = line.Split(",")
End If
Loop Until line Is Nothing
