title: ASP.NET Ajax not running with IIS 7
body: <p>I have a small web application with ASP.NET AJAX running well under the Cassini ASP.NET from <a href="http://www.ultidev.com/" rel="nofollow noreferrer">http://www.ultidev.com/</a>. But when I tried to host it under IIS7, the AJAX is not working. The UpdatePanel, the Calendar extension, the client side validation from the Validation Control are not working at all. I think it must be a problem of IIS 7. </p>
  
  <p>Here's a section of the web.config file:</p>
  
  <pre><code>    &lt;system.webServer&gt;
      &lt;validation validateIntegratedModeConfiguration="false"/&gt;
      &lt;modules&gt;
          &lt;remove name="ScriptModule"/&gt;
          &lt;add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/&gt;
      &lt;/modules&gt;
      &lt;handlers&gt;
  
  
       &lt;remove name="WebServiceHandlerFactory-Integrated"/&gt;
          &lt;remove name="ScriptHandlerFactory"/&gt;
          &lt;remove name="ScriptHandlerFactoryAppServices"/&gt;
          &lt;remove name="ScriptResource"/&gt;
          &lt;add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/&gt;
          &lt;add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/&gt;
          &lt;add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/&gt;
          &lt;add name="CrystalImageHandler.aspx_GET" verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" preCondition="integratedMode"/&gt;&lt;/handlers&gt;
  &lt;/system.webServer&gt;
