创建虚拟主机大体牵扯到用户、站点、目录、FTP、DNS等几项内容，此外，可能还有EMAIL。QWEB组件对此做了较全面的封装，需要的可以和qaymuic@163.com联系。
以下是创建一个虚拟主机的代码：
config.xml(配置信息）
<Root_Element>
<admin>Administrator</admin>
<adminpass>xxxxxx</adminpass>
<readuser>IUSR_MACHINE</readuser>
<domain>cocoo.net</domain>
<dnsadmin>dnsadmin</dnsadmin>
<dnsadminpass>yyyyy</dnsadminpass>
<dnsip>10.1.143.227</dnsip>
<group>tryit</group>
<webdir>http://hanhong.cocoo.net</webdir>
</Root_Element>
global.asa(配置文件）
<SCRIPT LANGUAGE=vbscript RUNAT=Server>
Sub Application_OnStart
set ff=server.createobject("microsoft.xmldom")
ff.async=false
ff.load server.mappath("config.xml")
set rootElem = ff.documentElement
for e1=0 to rootElem.childNodes.length-1
application(trim(rootElem.childNodes.item(e1).nodeName))=trim(rootElem.childNodes.item(e1).text)
next
End Sub
</script>
