How do I enable HTTP PUT and DELETE for ASP.NET MVC in IIS?

Question

I use HTTP PUT and DELETE in my ASP.NET MVC3 application. When I run it in local, every thing works correctly; But when I publish the application to the server, these methods do not work.

Are there any special settings for enable a web server to support PUT and DELETE requests? I'm using shared hosting with IIS 7.5.

UPDATE:

I enable PUT and DELETE requests in IIS manager. PUT command work fine. But DELETE still not works. I create requests by jQuery:

I'm in this page:

http://domain.com/dashboard/edit-site/103323/links/ 

and my ajax call is:

$.ajax({     // url: same as page-url,     cache: false,     type: 'DELETE',     data: { linkid: $(link).data("linkid") },     beforeSend: function () {         // doing something in UI     },     complete: function () {         // doing something in UI     },     success: function (data) {         // doing something in UI     },     error: function () {         // doing something in UI     } }); 

This will create a request like this:

Accept: */* Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Origin: http://domain.com Referer: http://domain.com/dashboard/edit-site/103323/links/ User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1 X-Requested-With: XMLHttpRequest 

With this Form Data:

linkid:104044

Go to Handler Mappings in your IIS Manager. Find ExtensionlessUrlHandler-Integrated-4.0, double click it. Click Request Restrictions... button and on Verbs tab, add both DELETE and PUT.

EDIT: Possible WebDav Publisher issue

You've mention on a deleted post you were running on a 2008 server right? Try removing webDav role, or disable it from your site config: on system.webServer -> modules section, remove WebDAVModule module:

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

Answer 2

If you are getting following error in your production environment in the asp.net web api on PUT or DELETE though these methods are working fine locally.

405 - http verb used to access this page is not allowed.

Just add following settings in your server's web.config

<system.webServer>     <handlers>       <remove name="WebDAV" />       <remove name="ExtensionlessUrlHandler-Integrated-4.0" />       <remove name="OPTIONSVerbHandler" />       <remove name="TRACEVerbHandler" />       <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />     </handlers>     <modules>         <remove name="WebDAVModule" />     </modules> </system.webServer> 

Cause: webDAV module blocks PUT/DELETE methods by default. So first remove this module and its handler. We first remove any existing ExtensionlessUrlHandler-Integrated-4.0 settings and add it with desired path and verbs.
