首先下载ajaxpro.dll，你可以从http://www.ajaxpro.info/获得。最新版本是7.7.31.1，下载解压后的文件夹中有个AjaxPro.dll，就是它了。使用VS2008新建web项目,并添加对AjaxPro.dll的引用，然后在Web配置文件中添加：
<httpHandlers>
<add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro"/>
</httpHandlers> 这个配置项表明所有的ajaxpro/*.ashx请求（即从客户发送的Ajax请求）都交给AjaxPro.AjaxHandlerFactory处理，而不是由默认的System.Web.UI.PageHandlerFactory来处理。
