AjaxToolkit IIS7 Asp.Net 4.0: Sys not defined; a problem with the handler?

Question

I moved the asp.net 3.5 application to asp.net 4.0 and moved from Windows 2003 (iis6) to Windows 2008 r2 (iis7.5), and now I have this sys is undefined error.

I have an application running in a federated application pool. everything works except my ajaxtoolkit 3.0.20820.0 dll

I have now read several blog posts, most of them cover asp.net 2.0 web.config files, not asp.net 4.0 minimal configuration files.

Here are some parts of my current configuration file:

 <system.webServer> <modules runAllManagedModulesForAllRequests="true"/> <validation validateIntegratedModeConfiguration="false"/> <handlers> <add name="AjaxToolkit" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="ChartImg" verb="*" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </handlers> 

and the other part:

 <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add verb="GET" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler" validate="false"/> <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" /> </httpHandlers> 

There is not much information on issues with asp.net 4.0 and ajaxtoolkit http handler, so I hope some guru @stackoverflow can help me :)

EDIT:

since I have this stupid sys undefined thing, my global.asax gives this on_Error:

 Error Message: This is an invalid script resource request. Stack Trace: at System.Web.Handlers.ScriptResourceHandler.ProcessRequest(HttpContext context) at System.Web.Handlers.ScriptResourceHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) 

on scriptresource.axd: S files

Edit2: it is strange that my local web.config has no handlers in web.config and runs on a development web server

Edit 3: people say Adrian has a solution here: http://budigelli.wordpress.com/2007/05/01/error-sys-is-undefined-error/ but I can't get it to work on IIS7

Edit 4: I read somewhere that IIS7 has wildcard matching in Handler mapping I saw that there is an asymmetric wildcard mapping in the sorted list above the .axd mapping. but now I don’t know yet how to configure mappings in IIS7 to support Ajaxtoolkit!

Answer 1

OK decided: I found this Cassiano comment at this address: http://madskristensen.net/post/Optimize-WebResourceaxd-and-ScriptResourceaxd.aspx

and then I realized that I have a URL rewriting extension in IIS7 that added a trailing slash to everything. (the rule was created by the rewrite component wizard)

here are my current parts of web.config that I used and had ajaxtoolkit to work with:

 <httpHandlers> <remove verb="*" path="*.asmx" /> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" /> <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" /> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </httpModules> 

and this part:

 <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules> <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </modules> <handlers> <remove name="WebServiceHandlerFactory-Integrated" /> <add name="test jp" path="*.axd" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" preCondition="classicMode,runtimeVersionv4.0,bitness32" /> <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" /> <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" /> <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" /> <add name="ChartImg" verb="*" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </handlers> 

Rule number 10: AjaxToolkit IIS7 Asp.Net 4.0: Sys not defined; handler transfer problem?

Answer 2

For asp.net 4.0 on IIS 7 and IIS 7.5, add this to your web.config:

 <system.webServer> <handlers> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </handlers> </system.webServer> 

UPDATE: I changed the version to the correct version for ASP.NET 4.0

Answer 3

In the past, we used ASP.NET AjaxToolkit and template, demo, or sample files that were submitted to web.config with the following

  <remove name="ScriptHandlerFactory"/> <remove name="ScriptHandlerFactoryAppServices"/> <remove name="ScriptResource"/> <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
