这个socket组件是由开发jmail的那家公司作的。
很老的一个版本了。不过挺好的。我一直在用。
比较稳定。以前发现xmlhttp在win2003 server上不太好。流量大了iis容易当掉。用这个组件倒还算稳定。

    paraHost ="www.knowsky.com"      ' host
    paraPort = 80                     ' port
    paraFileUrl ="/test/test.htm"
   
    Set Socket = CreateObject("Socket.TCP")
    Socket.Host = paraHost & ":" & paraPort
    Socket.Timeout = paraTimeout
    If Err.Number <> 0 Then Err.Clear
    Socket.open
    ' timeout error = 8000ffff
    Socket.SendLine "GET " & paraFileUrl & " HTTP/1.0"
    Socket.SendLine "HOST: " & paraHost
    Socket.SendLine ""
    Socket.SendLine ""
    'Sleep 200
    Socket.WaitForDisconnect
    If Err.Number <> 0 Then
        response.write Err.Number & " -- " & Err.Description

        Err.Clear
    Else
    response.write HTTPResponse(Socket.Buffer, 1)  ' output text from  socket
    End If
    Socket.Close
    Set Socket = Nothing

Private Function HTTPResponse(ByVal toHTTPResponse, ByVal whichHTTPResponse)
  On Error Resume Next
  Dim HTTPResponseDelimiter
 
  HTTPResponseDelimiter = Chr(13) & Chr(10) & Chr(13) & Chr(10)
  If (InStr(1, toHTTPResponse, HTTPResponseDelimiter, vbBinaryCompare) <> 0) Then
    Select Case whichHTTPResponse
    Case 0 'Header
      HTTPResponse = Mid(toHTTPResponse, 1, (InStr(1, toHTTPResponse, HTTPResponseDelimiter, vbBinaryCompare) - 1))
    Case 1 'Body
      HTTPResponse = Mid(toHTTPResponse, (InStr(1, toHTTPResponse, HTTPResponseDelimiter, vbBinaryCompare) + Len(HTTPResponseDelimiter)), (Len(toHTTPResponse) - (InStr(1, toHTTPResponse, HTTPResponseDelimiter, vbBinaryCompare) - 1)))
    End Select
  End If

End Function

利用Session限制重复操作的简单方法 ASP模仿asp.net的DataGrid
