遇旷世难题，寒风中跪地裸求！

我用VB编写了了Http发送程序，往Apache Tomcat发送请求，两种不同的发送方法，但是返回的结果确实不一样，因为需要设置超时，所以需要采用第二种方法来做，但是目前第二种方法未通过，恳请高人指点问题出处！

XMLHTTP方式:
Set xmlsend = CreateObject("MSXML2.XMLHTTP")
xmlsend.open "post", "http://172.16.0.204:8010/B2EC/E2BServlet", False
xmlsend.setRequestHeader "Content-Type", "text/xml;charset=GB2312"
xmlsend.send ("<?xml version='1.0' encoding='GBK'?><test><sendtext>测试</sendtext><test>")
If xmlsend.Status = "200" Then
recstr = xmlsend.responseText
Else
erromsg = xmlsend.responseText
End If

/*******************************发送内容格式:*****************************************************/
POST /B2EC/E2BServlet HTTP/1.0
Accept: */*
Accept-Language: zh-cn
Content-Type: text/xml;charset=GB2312

<?xml version='1.0' encoding='GBK'?><test><sendtext>测试</sendtext><test>

/*****************************返回正确信息,没有问题*************************************************/


ServerXMLHTTP方式：
Set xmlsend = CreateObject("MSXML2.ServerXMLHTTP")
xmlsend.setTimeouts 60000, 60000, 100000,100000
xmlsend.open "post", "http://172.16.0.204:8010/B2EC/E2BServlet", False
xmlsend.setRequestHeader "Content-Type", "text/xml;charset=GB2312"
xmlsend.send ("<?xml version='1.0' encoding='GBK'?><test><sendtext>测试</sendtext><test>")
If xmlsend.Status = "200" Then
recstr = xmlsend.responseText
Else
erromsg = xmlsend.responseText
End If

/*******************************发送内容格式:*******************************************************/
