在JSP中使用xmlhttp进行数据交互

Domain = " test.com" 
sXml = "<?xml version=""1.0"" encoding=""gb2312"" ?>" &_ 
"<Package>" &_ 
"<Domain>" & Domain & "</Domain>" &_ 
"</Package>" 
Set oD = Server.CreateObject("Microsoft.XMLHTTP") 
oD.Open "Post", "http://Server/Domain_Check.jsp", False 
oD.Send(sXml) 

If oD.Status = 200 Then 
Result = oD.responseText 
Set o = Server.CreateObject("Microsoft.XMLDOM") 
o.LoadXML(Result) 

Domain = CInt(o.selectSingleNode("//Result").text) 
Response.Write Domain 
Set o = Nothing 
Set oD = Nothing 
End If
