解决ASP.NET 在IIS 7中提示EXT未定义的错误

[html]
    在系统升级到WINDOWS SERVER 2008 R2后IIS也升级到7.0版本，在发布网站后提示错误：EXT未定义。经过分析，发现是再程序中引用了AJAX的原因，需要在web.config中单独配置，配置的代码如下： 
  
[html]
FOR IIS 6.0 and earlier   
  
  
  
Add the following to <httpModules> section under <system.web> section in web.config: 

 
<add name="AjaxRequestModule" type="Coolite.Ext.Web.AjaxRequestModule, Coolite.Ext.Web" /> 
  
Add the following to <httpHandlers> section under <system.web> section in web.config: 
  
 
<add path="*/coolite.axd" verb="*" type="Coolite.Ext.Web.ResourceManager" validate="false" /> 
  
FOR IIS 7.0, add the following to <system.webServer> 
 
  
 
<system.webServer> 
<validation validateIntegratedModeConfiguration="false"/> 
    <modules> 
        <add name="AjaxRequestModule" preCondition="managedHandler" type="Coolite.Ext.Web.AjaxRequestModule, Coolite.Ext.Web" /> 
    </modules> 
    <handlers> 
        <add name="AjaxRequestHandler" verb="*" path="*/coolite.axd" preCondition="integratedMode" type="Coolite.Ext.Web.ResourceManager"/> 
    </handlers> 
</system.webServer>
