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：

[解决办法]
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
