AjaxToolkit IIS7 Asp.Net 4.0: Sys is not defined; handler mapping issue? - httphandler

Question

I have moved my asp.net 3.5 app 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 the app running in an integrated application pool. everything works except my ajaxtoolkit 3.0.20820.0 dll
now I have read several blog posts, most of them cover asp.net 2.0 web.config files and not the minimized asp.net 4.0 config files.
here are some parts from my current config 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 another 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 info available for asp.net 4.0 and ajaxtoolkit http handler issue, so I hope some guru # stackoverflow can help me out :)
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)
it's on scriptresource.axd files :S
Edit2: the strange thing is that my local web.config hasn't got any handler stuff in the web.config and it runs on the development webserver casini
Edit 3: people say that Adrian has the 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've read somewhere that IIS7 has a wildcard mapping at Handler mapping
I have seen that there is an extensionless wildcard mapping in de sorted list above the .axd mapping. but now I still don't know how to configure the mappings in IIS7 to support the Ajaxtoolkit!

Answer 1

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 have changed the version to the correct version for ASP.NET 4.0

OK solved it:
I found this comment of Cassiano at this URL:
http://madskristensen.net/post/Optimize-WebResourceaxd-and-ScriptResourceaxd.aspx
and then I realized that I had the URL rewriting extension in IIS7 which appended a trailing slash to everything. (the rule was generated by the wizard of the rewriting component)
here is my current web.config parts which i used and had ajaxtoolkit to work:
<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" />

</handlers>

AjaxToolkit IIS7 Asp.Net 4.0: Sys is not defined; handler mapping issue?

Answer 3

In the past we used the ASP.NET AjaxToolkit and the template, demo, or example files shipped which a 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"/>
