Smarthttp Simple HttpRequest Class (ASP) _ Application Skills

Simplest method of invocation:
Response.Write smarthttp ("http://www.baidu.com/"). Send (). GetText ()

Complex call
Set myhttp = Smarthttp ("http://www.baidu.com/s", "get")
Myhttp.dataset.append "WD", "Smarthttp"
Myhttp.send ()
Response.Write Myhttp.gettext ("GBK")
