I'm trying to run my dotnet core app in IIS Clustered environment. It runs perfectly when shared configuration is disabled. But soon I enable shared configuration, the application fails to start, and gives error:
HTTP Error 500.21 - Internal Server Error
Handler "ExtensionlessUrl-Integrated-4.0" has a bad module "ManagedPipelineHandler" in its module list
I had been looking for the solution since few days, but nothing worked for me. Mostly posts at SO ask to install/reinstall .NET 4/4.5 etc, but this isn't applicable in my case, as it is already updated.
Following are the concerned section of my configuration
(I can provide more if needed)
Web.config:
...
<handlers>
<remove name="WebDAV" />
<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" />
</handlers> ...
Shared applicationHost.config:
<handlers>
...
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />

</handlers>
...
...
<modules>
...
<add name="ApplicationInitializationModule" lockItem="true" />
<add name="AspNetCoreModule" />
<add name="RewriteModule" />
<add name="ApplicationRequestRouting" />
</modules>
Is there something I am missing?
The app runs fine when disable shared configuration of IIS, or when run through .exe. So I believe the required features are installed. Is there any feature/package specifically required for shared configuration case? Please guide.
I'm trying to build a simple Web API service (Visual Studio, C#, local IIS) that has an http handler that accepts PUT and other requests
After getting everything configured, I'm trying to test the PUT event and am receiving
HTTP Error 405.0 - Method Not Allowed error.
Module WebDAVModule
Notification MapRequestHandler
Handler WebDAV
Error Code 0x00000000
Google searches revealed that WebDAV intercepts PUT commands, so I am removing it from web.config:
<system.webServer>
<handlers accessPolicy="Read, Execute, Script">
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="WebDAV"/>
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
I'm afraid to uninstall WebDAV from my dev box, as it may break other web projects that do rely on the module.
What am I doing wrong?
Adding this snippet can resolve your problem:
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true" />
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />

</handlers>
</system.webServer>
I have an Azure Website setup, and I'm trying to point .html to .net 4.5 because I want MVC to route the request for the extension, and I believe that IIS is routing it and it's never making it to mvc/asp.net to decide where to go.
There is a Handler Mappings section, but I'm not sure what to put for the script processor path.
I'm not sure but I guess you can map it to System.Web.UI.PageHandlerFactory
The Script Processor value should be "The absolute path to the FastCGI application." More details found here
Settings -> Configuration -> Path Mappings
The ScriptProcessor will be reference to one of the available handler mappings installed on IIS.
https://learn.microsoft.com/en-us/iis/configuration/system.webserver/handlers/
If you want to see the available Script mappings then you can do this.
Go to the App Services Portal
Open App Service for Windows
Click 'Go' under Advanced Tools
In Kudu go to Debug Console
Find and open ApplicationHost.config.
You’ll see some examples under there.
<handlers accessPolicy="Read, Script">
<add name="PHP56_via_FastCGI" path="*.php" verb="GET,HEAD,POST" modules="FastCgiModule" scriptProcessor="D:\Program Files (x86)\PHP\v5.6\php-cgi.exe" resourceType="Either" />

I've made a simple Sencha Touch web application and deployed it to Azure to try Azure out. One of the first things Sencha Touch does is try to download an app.json file. On IIS I'd normally enable json in the mime types section, but I have not been able how to figure this out how to do this using the Azure Web Console. Consequently, a 404 error is returned when the app performs an XMLHttpRequest to get the file.
I've seen some post on SO about adding .json to the web.config and I tried the following, to no avail:
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<staticContent>
<remove fileExtension=".json"/>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
The web app is here.
http://nsgapp.azurewebsites.net
Any input on how to enable an Azure shared-instance to serve .json files is greatly appreciated.
Nevermind, it was a silly error. I have two websites... one that serves the sencha web app and an ASP.NET MVC WebAPI site for the webservices. I was enabling json on the latter, when I should have been enabling it on the former because app.json is in served from the actual client application. So, the correct way to enable azure to download static json files is to make sure you have this:
<system.webServer>
<staticContent>
<remove fileExtension=".json"/>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
</system.webServer>
in the web.config.
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" />
To get PUT and DELETE to be accepted by IIS 7.5 for a PHP 5.4 fast-CGI driven REST API I had to disable the WebDAV-module. Otherwise the WebDAV module intervenes the HTTP requests using PUT or DELETE. To get this working was however a bit confusing and I might have missed some steps or done it in another order.
These lines are placed as children of the <system.webServer>-element in web.config in the application root.
<modules>
<remove name="WebDAVModule" />
</modules>
<handlers>
<remove name="WebDAV" />
</handlers>
Hopes this might spare some frustration. It seems like the default setting for the server is to accept any HTTP verb not listed - see settings under Request filtering -> HTTP Verbs -> Edit feature Settings. One may consider to explicitly add the VERBS that are to be allowed. The verbs allowed may be specified appending this snippet, also as a child of <system.webServer>.
<security>
<requestFiltering>
<verbs allowUnlisted="false">
<add verb="GET" allowed="true" />
<add verb="POST" allowed="true" />
<add verb="DELETE" allowed="true" />
<add verb="PUT" allowed="true" />
</verbs>
</requestFiltering>
</security>
On a client machine one can uninstall the WebDAV module from here:
Control Panel -> Uninstall Program -> Turn Windows features on or off -> IIS -> World Wide Web Services -> Common HTTP feautre -> WebDAV Publishing
The last measure to get it working was by editing applicationhost.config found in C:\Windows\System32\inetsrv\config. Within <system.webServer> -> <handlers> you will see a php entry that has just verb="GET,HEAD,POST - amend it to add the verbs you require, e.g.:
<add name="PHP54_via_FastCGI" path="*.php" verb="GET,HEAD,PUT,DELETE,POST"/>

append verbs here ----------------------------------------------|
1.Go to IIS Manager.
2.Click on your app.
3.Go to "Handler Mappings".
4.In the feature list, double click on "WebDAV".
5.Click on "Request Restrictions".
6.In the tab "Verbs" select "All verbs" .
7.Press OK.
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".
My scenario was a web application in a web site on IIS 7.5. The web site had to continue to enable WebDAV, but the web application needed to turn it off in order to support PUT and DELETE in its REST API.
To get that working, the web application's Web.config needed this:
<modules runAllManagedModulesForAllRequests="true" runManagedModulesForWebDavRequests="true" >
<remove name="WebDAVModule" />
</modules>
<handlers>
<remove name="WebDAV" />
</handlers>
The important difference from the other answers here is the need for runManagedModulesForWebDavRequests="true"
For me this does the trick in the web.config.
<system.webserver>
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<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" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
<system.webserver/>
<system.web>
<authentication mode="Windows" />
<identity impersonate="true"/>
<system.web/>
I used following configuration:
IIS 7.5
Windows Server 2008 R2
Custom Application Pool, .NET 4.0, Integrated
Windows Authentication = true
Anonymous Authentication = false
Hope it helps. ;-)
URLScan tool users
If other answers still don't work and you get 404 error: these verbs may be explicitly rejected by the URLScan tool, if you have it installed.
You can configure [AllowVerbs] and [DenyVerbs] sections of the URLScan.ini file to meet your needs.
Beware of the security risks of enabling these verbs.
What worked for me was uninstalling WebDav completely.
Going into the handler mappings and setting WebDAV to handle all verbs is the only thing that worked for me, despite the fact that PUT and DELETE were already listed as handled verbs. The working web.config I have is:
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
<remove name="WebDAV" />
<add name="WebDAV" path="*" verb="*" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" />
</handlers>
</system.webServer>
in the web.config
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
you can also use the IIS management UI and define this globally, or default web server
I tried in IIS 8.
**uninstall WebDav Publishing

featues on or off-> Select Internet Information Services->World Wide
Web Services->Common HTTP Featues->"Remove" WebDAV Publishing by unchecking WebDAV option**
Reason for 500 error !
Hi all,
I want to post my own research too, I hope it would help future enthusiasts.
As suggested in answers, I can't uninstall WebDav so I have added the line below in web config (from other answers)
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
but I got a 500 error, when I have enabled debug mode found this
Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'ExtensionlessUrlHandler-Integrated-4.0'
Answer
Its because there was already an ExtensionlessUrlHandler in the handler mappings section, do the following to resolve the issue.
Method 1
1) Go to Your IIS Manager and select your app
2) Go to Handler Mappings feature
3) Find ExtensionlessUrlHandler-Integrated-4.0 and delete it.
4) Add ExtensionlessUrlHandler in your webconfig (as mentioned in above answers)
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
Method 2
1) Remove ExtensionlessUrl handler from your web config
2) Click on your app in IIS Server, go to HandlerMappings
3) Find ExtensionlessUrlHandler-Integrated-4.0 (only this name, ignore others)
4) right click on it and choose Edit
edit handler
5) click on 'Request Restrictions' and select Verbs tab & choose All Verbs
this will enable extensionsless handler to allow all verbs.
I will go with method 1, as we can have control in web.config. But make sure you
check the deployment server for duplicate handler definitions.
My web.config with asp.net core 1.0
<?xml version="1.0" encoding="utf-8"?>

</system.webServer>
</configuration>
In windows server 2012.
Open applicationHost.config file in notepad with Administrator rights
applicationHost.config file is found in C:\Windows\System32\inetsrv\config
Locate the section
<verbs allowUnlisted="false" applyToWebDAV="true">
<add verb="GET" allowed="true" />
<add verb="HEAD" allowed="true" />
<add verb="POST" allowed="true" />
<add verb="DELETE" allowed="false" />
<add verb="TRACE" allowed="false" />
<add verb="PUT" allowed="false" />
<add verb="OPTIONS" allowed="false" />
</verbs>
Notice DELETE and PUT HTTP Verbs are set to false.
Change them to true.
It should now read as below
<verbs allowUnlisted="false" applyToWebDAV="true">
<add verb="GET" allowed="true" />
<add verb="HEAD" allowed="true" />
<add verb="POST" allowed="true" />
<add verb="DELETE" allowed="true" />
<add verb="TRACE" allowed="false" />
<add verb="PUT" allowed="true" />
<add verb="OPTIONS" allowed="false" />
</verbs>
Save the file. You have enabled HttpPut and HttpDelete requests on your web server
The main solution is to remove webdavmodule from the specific website'd module's section.
So you can do it from both IIS and in webconfig.
I was dealing with the same problem. The solution for me was to turn off the Firewall mode of the Web Application in Plesk Panel.
