最简单的调用方法：
response.write SmartHttp("http://www.gxlsystem.com/").send().gettext()

复杂调用
set myhttp = SmartHttp("http://www.gxlsystem.com/s","GET")
myhttp.dataset.append "wd","smarthttp"
myhttp.send()
response.write myhttp.gettext("gbk")

代码如下:

<script language="jscript" runat="server"> 
function SmartHttp(url,method,data){ 
return new _SmartHttp(url,method,data); 
} 

function _SmartHttp(url,method,data){
