iis - ASP.NET Handle PUT/DELETE verbs

Question

This applies to ASP.NET in general but also Web API.

How can we handle PUT/DELETE verbs without enabling RAMMFAR (RunAllManagedModulesForAllRequests).

I can't configure the handler mapping within IIS as my site is hosted on an Azure Web Role and any changes I make will not be persisted.

@Alexander's answer put me on the right track. Had to add the following to get DELETE/PUT handled by ASP.NET:

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="false"/>
    <handlers>
      <remove name="ExtensionlessUrl-Integrated-4.0" />
      <add name="ExtensionlessUrl-Integrated-4.0" 
           path="*." 
           verb="GET,HEAD,POST,DEBUG,DELETE,PUT" 
           type="System.Web.Handlers.TransferRequestHandler" 
           preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
  </system.webServer>
