I\'m writing a program in vb 6. I want to send data to my server and get returned data but I faced a problem: when I send data( without any error) there is no answer from my server.

I'm writing a program in vb 6. I want to send data to my server and get returned data

but I faced a problem: when I send data( without any error) there is no answer from my server.

Note: I'm using XAMPP as server and it's ok with browser!!!

Private blnConnected As Boolean


Private Sub cmdSend_Click()
    Dim str As String
    str = "GET /newpass/ HTTP/1.1" & vbNewLine & "Host: localhost" & _
        vbNewLine & "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.21) Gecko/20110830 Firefox/3.6.21" & _
        vbNewLine & "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" & _

    winsock.Protocol = sckTCPProtocol
    winsock.RemoteHost = "localhost"

        DoEvents
    Wend


    winsock.SendData str

End Sub


Private Sub winsock_Connect()
 blnConnected = True
End Sub

Private Sub winsock_DataArrival(ByVal bytesTotal As Long)
    Dim strResponse As String
    winsock.GetData strResponse, vbString, bytesTotal
    info.Text = strResponse
End Sub

Private Sub winsock_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
winsock.Close
End Sub


Try adding 2 newlines after your last header. That will indicate to the server that the headers are complete.

str = "GET /newpass/ HTTP/1.1" & vbNewLine & "Host: localhost" & _
        vbNewLine & "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.21) Gecko/20110830 Firefox/3.6.21" & _
        vbNewLine & "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" & _
        vbNewLine & "Accept-Language: en-us,en;q=0.5" & _
        vbNewLine & "Accept-Encoding: gzip,deflate" & _
        vbNewLine & "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7" & _
        vbNewLine & "Keep-Alive: 115" & _
        vbNewLine & "Connection: keep-alive" & vbNewLine & vbNewLine
