    前面一部分把Microsoft.Web.Extensions里的控件的前缀设成asp，后面一部分则替换了原有的验证控件。

    httpHandlers/httpModules部是这样的，

<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="Microsoft.Web.Script.Services.ScriptHandlerFactory, 
Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpHandlers>
<httpModules>
<add name="WebResourceCompression" type="Microsoft.Web.Handlers.WebResourceCompressionModule, Microsoft.Web.Extensions, 
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add name="ScriptModule" type="Microsoft.Web.UI.ScriptModule, Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35"/>
</httpModules> 

    前面一部分换掉了处理Web服务(*.asmx)的引擎，后面则在处理管道里添加 webresource.axd 资源压缩和脚本模块。脚本模块处理了3个事件，

protected virtual void Init(HttpApplication context)
{
context.PreSendRequestHeaders += new EventHandler(this.PreSendRequestHeadersHandler);
context.PostAcquireRequestState += new EventHandler(this.OnPostAcquireRequestState);
context.AuthenticateRequest += new EventHandler(this.AuthenticateRequestHandler);
}

 对PreSendRequestHeaders事件，处理重新定向，把重新定向的地址写到回复数据里

private void PreSendRequestHeadersHandler(object sender, EventArgs args)
{
HttpApplication application1 = (HttpApplication) sender;
if (PageRequestManager.IsAsyncPostBackRequest(application1.Request.Headers))
{
HttpResponse response1 = application1.Response;
if (response1.StatusCode == 0x12e)
{
string text1 = response1.RedirectLocation;
List<HttpCookie> list1 = new List<HttpCookie>(response1.Cookies.Count);
for (int num1 = 0; num1 < response1.Cookies.Count; num1++)
{
list1.Add(response1.Cookies[num1]);
}
response1.ClearContent();
response1.ClearHeaders();
for (int num2 = 0; num2 < list1.Count; num2++)
{
response1.AppendCookie(list1[num2]);
}
response1.Cache.SetCacheability(HttpCacheability.NoCache);
response1.ContentType = "text/plain"
response1.Write(PageRequestManager.EncodeString("pageRedirect", string.Empty, text1));
}
}
}

对AuthenticateRequest事件，设置了是否跳过授权

private void AuthenticateRequestHandler(object sender, EventArgs e)
{
HttpApplication application1 = sender as HttpApplication;
if ((application1 != null) && ScriptModule.ShouldSkipAuthorization(application1.Context))
{
application1.Context.SkipAuthorization = true;
}
} 
 

对PostAcquireRequestState事件，则是用来调用页面的静态PageMethod的!

private void OnPostAcquireRequestState(object sender, EventArgs eventArgs)
{
HttpApplication application1 = (HttpApplication) sender;
HttpRequest request1 = application1.Context.Request;
if (RestHandler.IsPageMethodCall(request1))
{
WebServiceData data1 = WebServiceData.GetWebServiceData(HttpContext.Current, request1.FilePath, false, true);
string text1 = request1.PathInfo.Substring(4);
WebServiceMethodData data2 = data1.GetMethodData(text1);
RestHandler.ExecuteWebServiceCall(HttpContext.Current, data2);
application1.CompleteRequest();
}
}
