用w3Socket替代xmlhttp后的问题，高手Help
因为xmlhttp老是超时假死，serverxmlhttp经常抓不到目标站（如百度这些都有防采集的）。找了好久发现w3Socket这个asp组件，一开始能工作，但后来就经常报错，
Timeout expired while waiting for socket event

代码是这样的。调用函数GetHtml("www.auak.com","/")

JScript code


    Function GetHtml(paraHost,paraFileUrl)
        Dim Socket
        on error resume next 
        Set Socket =Server.CreateObject("Socket.TCP")
        Socket.Host = paraHost & ":80"
        Socket.Timeout =80*1000 '80秒
        If Err.Number <> 0 Then err.Clear
        Socket.open
        Socket.SendLine "GET " & paraFileUrl & " HTTP/1.0"
        Socket.SendLine "HOST: " & paraHost
        Socket.SendLine ""
        Socket.SendLine ""
'        Sleep 200
        Socket.WaitForDisconnect
        If Err.Number <> 0 Then
            GetText = ""
'            response.write Err.Number & " -- " & Err.Description
            Err.Clear
        Else
            GetText = ParseRet(Socket.Buffer, 1)     ' output text from     socket 
        End If
        Socket.Close
        Set Socket = Nothing
    End Function

这个控件貌似有问题要不就是asp问题

使用xmlhttp比较多：

Error while processing Socket opperation: No Data; perhaps no route to host

错误处理的操作：插座没有数据；或者主机不可达
