IIS 7.5 + enable PUT and DELETE for RESTFul servic

Question

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 "http://localhost/MyService/Resource.Something.manifest"

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.

<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />

See http://learn.iis.net/page.aspx/901/iis-express-faq/ that is linked from the OR wiki.

From the link (not block-quoted for readability):

A: You can modify the IIS Express applicationHost.config in the %userprofile%\documents\IISExpress\config folder. For example to enable PUT and DELETE for extensionless Urls scroll down to the bottom of the IIS Express applicationHost.config file and look for a handler entry that starts with:

<add name="ExtensionlessUrl-Integrated-4.0" …

In the verb attribute add PUT and DELETE so the verb attribute looks like: verb="GET,HEAD,POST,DEBUG,PUT,DELETE".
