Who else is tired of Cloudflare giving you the 505 slap? - Mike Tyler - Sep 19, 2013

Every other site now has this damn "please wait 5 secs" rule before you can access the actually website.
You can use this code to bypass cloudflare as well to the other bullshit dos protectors.

The reason you get a 505 error and what's basicily going on with your request when the dos protector gets
you is that it cuts you off before you can reach and get the required cookies to verify your request.

After some researching, I found out that webbrowser could sucesfully both connect, wait and get the cookies
you need to make a request 😈

Here's how I bypassed Cloudflare...

1. Get site's cookie with good old webbrowser.
2. Put application in sleep for 5 secs.
2. Use webbrowser's cookie in your http request (yea, it's dat smooth)

Code 
Private Function GetWebbrowserCookie()

  WebBrowser1.Navigate("http://URL")

  'Wait 2-5 secs

  Return WebBrowser1.Document.Cookie

    End Function

    Public Function GETHTTP(ByVal url As String) As String

  Dim result As String = Nothing

  Try

    'Create request

    Dim postReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)

    postReq.Method = "GET"

    postReq.UserAgent = "Mozilla/5.0 (Windows NT 6.2; rv:22.0) Gecko/20100101 Firefox/22.0"

    postReq.ContentType = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"

    [b]postReq.Headers.Add("Cookie", GetWebbrowserCookie)[/b]

    'Get response

    Dim postresponse As HttpWebResponse

    postresponse = DirectCast(postReq.GetResponse(), HttpWebResponse)

    'Read response

    Dim postreqreader As New StreamReader(postresponse.GetResponseStream)

    result = postreqreader.ReadToEnd

    postreqreader.Close()

  Catch ex As WebException

    'fuck

  End Try

  Return result

    End Function

preferably you want to put the webbrowser in it's own thread so it dosn't freeze your application but choice up to you.

Code 
    Private Class CreateWebbrowser

        Dim url As String

        Dim _cookie As String

        Public Sub New(ByVal _url As String)

            url = _url

        End Sub

        Public Function GetCookie() As String

            Dim __threadStart As New ThreadStart(AddressOf _GetCookie)

            Dim __thread As New Thread(__threadStart)

            __thread.SetApartmentState(ApartmentState.STA)

            __thread.Start()

            __thread.Join() 'waits for application to finish

            Return _cookie

        End Function

        Private Sub _GetCookie()

            Dim __WebBrowser As New WebBrowser()

            __WebBrowser.ScrollBarsEnabled = False

            __WebBrowser.ScriptErrorsSuppressed = True

            __WebBrowser.Navigate(url)

            AddHandler __WebBrowser.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf WebBrowser_DocumentCompleted)

            While __WebBrowser.ReadyState <> WebBrowserReadyState.Complete

                Application.DoEvents()

            End While

            __WebBrowser.Dispose()

        End Sub

        Private Sub WebBrowser_DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs)

            Dim __WebBrowser As WebBrowser = DirectCast(sender, WebBrowser)

            __WebBrowser.ScrollBarsEnabled = False

            _cookie = __WebBrowser.Document.Cookie 'this get's the cookie

        End Sub

    End Class

peace.

you can wait 5 seconds or you can wait til your computer die off cuz that httpwebrequest is not going to connect to a dos protected website without cookie. ofc if you not one of those guys using webbrowser.. are you?
