sending HTTP POST request using SOCKETS

[intes2010]

I have here a working HTTP request using SOCKETS but I do not know how to send POST requests.

Here is my code:

 Dim hostName As String
            Dim hostPort As Integer
            Dim response As Integer
            Dim iphe As IPHostEntry = Dns.GetHostEntry("www.yellowpages.com")
            hostName = iphe.AddressList(0).ToString()
            hostPort = 80
            response = 0

            Dim host As IPAddress = IPAddress.Parse(hostName)
            Dim hostep As New IPEndPoint(host, hostPort)
            Dim sock As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
            sock.Connect(hostep)

            Dim request = "GET /nationwide/mip/choice-hotels-international-462092189/send_email?lid=161004592 HTTP/1.1" & vbCr & vbLf &
                          "Host: 208.93.105.105" & vbCr & vbLf &
                          "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36" & vbCr & vbLf &
                          "Connection: keep-alive" & vbCr & vbLf &
                          "Content-Type: application/x-www-form-urlencoded" & vbCr & vbLf &
                          "Content-Length: 0" & vbCr & vbLf & vbCr & vbLf

            response = sock.Send(Encoding.UTF8.GetBytes(request))
            response = sock.Send(Encoding.UTF8.GetBytes(vbCr & vbLf))

            sock.Close()

I wanted to fill-up this webform i have mentioned in my code with these data:

email%5Bto_address%5D=[e-mail]&email%5Bfrom_name%5D=Test Name&email%5Bfrom_address%5D=[e-mail]&email%5Bnote%5D=Hello

How do I do it? I have successfully done this using HttpWebRequest using the code below:

Dim cweb As String = "http://www.yellowpages.com/novato-ca/mip/creative-memories-consultant-senior-director-461725587/send_email?lid=171673036"
        Dim POST As String = "&email%5Bto_address%5D=[e-mail]&email%5Bfrom_name%5D=Test Name&email%5Bfrom_address%5D=[e-mail]&email%5Bnote%5D=Hello There"       

        Dim request As HttpWebRequest
        Dim response As HttpWebResponse

        request = CType(WebRequest.Create(cweb), HttpWebRequest)
        request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36"
        request.AllowAutoRedirect = True
        request.ContentType = "application/x-www-form-urlencoded"
        request.ContentLength = POST.Length
        request.Method = "POST"
        request.KeepAlive = True

        Dim requestStream As Stream = request.GetRequestStream()
        Dim postBytes As Byte() = Encoding.ASCII.GetBytes(POST)
        requestStream.Write(postBytes, 0, postBytes.Length)
        requestStream.Close()

        response = CType(request.GetResponse(), HttpWebResponse)
        response.Close()

But I wanted to recreate this concept by the use of SOCKETS.
