i am trying to understand how IIS 7.5 handles POST and PUT request. 

I am writing a RESTful service using OpenRasta framework. The POST operation works without any problem, but the PUT operation for the same URL does not. It returns error like the following

    Detailed Error Information
    Module: IIS Web Core
    Notification: MapRequestHandler
    Handler: StaticFile
    Error Code: 0x80070002

the url is like this following &quot;http://localhost/MyService/Resource.Something.manifest&quot;

Same setup works fine in visual studio development IIS.

**Solution**

Basically the default ExtensionlessUrlHandler does not accept PUT and DELETE verb. Just need to add them.

    &lt;add name=&quot;ExtensionlessUrlHandler-ISAPI-4.0_64bit&quot; path=&quot;*.&quot; verb=&quot;GET,HEAD,POST,DEBUG,PUT,DELETE&quot; modules=&quot;IsapiModule&quot; scriptProcessor=&quot;C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll&quot; resourceType=&quot;Unspecified&quot; requireAccess=&quot;Script&quot; preCondition=&quot;classicMode,runtimeVersionv4.0,bitness64&quot; responseBufferLimit=&quot;0&quot; /&gt;
