downloadstring

I am running this piece of code to get the source of my webpage.

The problem is why this function returns 404 error?

Private Function getPageSource(ByVal URL As String) As String
    Dim webClient As New System.Net.WebClient()
    Dim strSource As String = webClient.DownloadString(URL)
    webClient.Dispose()
    Return strSource
End Function
