Can't get WebApplicationContext object from ContextRegistry.GetContext(): Resource handler for the 'web' protocol is not defined

I'm stucked in configuring my web.config file under a web forms project in order to get an instance of WebApplicationContext (at Global.asax) and then being able to use scope="application | session | request"
<sectionGroup name="spring"> <section name="context" type="Spring.Context.Support.WebContextHandler, Spring.Web"/> <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" /> </sectionGroup>  <spring> <context type="Spring.Context.Support.WebApplicationContext, Spring.Web"> <resource uri="~/Configuration/Spring.xml" /> </context> </spring>  <httpHandlers> <add verb="*" path="*.aspx" type="Spring.Web.Support.PageHandlerFactory, Spring.Web"/> </httpHandlers>  <httpModules> <add name="Spring" type="Spring.Context.Support.WebSupportModule, Spring.Web"/> </httpModules>
I'm then trying to add the WebApplicationContext to my Application object, in order to cosume on any .aspx page;
protected void Application_Start(object sender, EventArgs e) { //Exception happens on next line! Application.Add("ContainerID", ContextRegistry.GetContext()); }
Exception I'm getting is;
"Error creating context 'spring.root': Resource handler for the 'web' protocol is not defined. Spring.NET"

Add this to system.webServer config node:
<modules runAllManagedModulesForAllRequests="true">
  <add name="Spring" preCondition="integratedMode" type="Spring.Context.Support.WebSupportModule, Spring.Web"/>
</modules>   
If you use integratedMode in IIS7
