IIS 7.5 and Web API 2 PUT/DELETE Requests

asp.net-web-api, iis, iis-7.5

Solution

Seems if I missed the 'HttpHandler' remove of WebDav. The following works:

<system.webServer>
   <modules>
      <remove name="WebDAVModule" />
   </modules>
   <handlers>
      <remove name="WebDAV" />
   </handlers>
</system.webServer>

Problem

This seems to be a common problem but I've troubleshot all the other techniques people are getting and had no luck, so here goes: I'm running WebAPI2 along with IIS7.5 on Windows Server 2010. In development my PUT/DELETE requests started working after I added the PUT/DELETE Handlers in HTTP Handlers of IIS. However, once I rolled to prod and applied the same changes I got no such luck. Heres my setup: WebConfig Server: Requests: ``` Request URL:http://dev.myserver.com/myapp/api/apps/76a09a7b-0750-4045-a3ce-696df0ff179c Request Method:PUT Status Code:405 Method Not Allowed 405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access. ``` Response Headers: ``` Allow:GET, HEAD, OPTIONS, TRACE Content-Length:1293 Content-Type:text/html Date:Thu, 21 Nov 2013 15:43:44 GMT Server:Microsoft-IIS/7.5 X-Powered-By:ASP.NET ``` Obliviously its mad because that verb is not acceptable but the configuration shows that it is. I saw another article talking about removing the WebDav Module from the Modules in IIS, however, once I did that I got a 500 Internal Server Error ( probably because its needed hehe ). Like I said this code is working correctly in dev so I'm not sure what the disconnect is.
