-- 网页无响应代码优化
老师好，我用这个检测网页无响应，实际这个是正常运行可以正常访问的，但是下面这个代码却显示有问题。。
try
Dim req = CType(System.Net.WebRequest.CreateDefault(New Uri("http://www.yijiansoft.net:81/srqcx.htm")), System.Net.HttpWebRequest)
req.Method = "HEAD"
req.Timeout = 1000
Dim res As System.Net.HttpWebResponse = req.GetResponse()
catch ex As System.Net.WebException
output.show(Date.now & "无响应")
End try

我网站关闭重新打开后，就会出现这种交替的，
但实际网页是正常的可以显示的
try
Dim req = CType(System.Net.WebRequest.CreateDefault(New Uri("http://www.yijiansoft.net:81/srqcx.htm")), System.Net.HttpWebRequest)
req.Method = "HEAD"
req.Timeout = 1000
Dim res As System.Net.HttpWebResponse = req.GetResponse()
output.show(Date.now & "正常")
catch ex As System.Net.WebException
output.show(Date.now & "无反应")
End try
