I am using WebAPI PUT and DELETE methods to perform actions from my website via AJAX using jQuery. My server is Windows Server 2008 R2 with Plesk installed. POST and GET requests work just fine, but PUT and DELETE fail.
I was originally getting a 401 Unauthorized response when I first deployed my site to the server. I then performed some actions and it turned into 405 Method not allowed.
I am now at a point where I'm receiving an Internal Server error:
Handler “ExtensionlessUrlHandler-Integrated-4.0” has a bad module “ManagedPipelineHandler” in its module list
Now, there are lots of posts about this, and sadly I can't get it to work yet.
Here's what I've tried:
- Added remove tags within
web.configfor WebDAV handler and module - Set permissions to execute scripts and executables within Handler Mappings
- Adding the PUT and POST verbs to within IIS
- Added PUT and POST verbs to the
web.config - Downloading the .NET Framework and performing a 'repair'
- Re-registered .NET Framework as shown in this answer
- Investigated CORS but I'm not doing any cross site scripting, It's just AJAX called from the same domain
How can I get rid of this message and allow my PUT and DELETE to work?
Heres my web.config

An extract from my web.config around the ExtensionlessUrlHandler-Integrated-4.0.
Looking at the difference between yours and mine I don't have this section resourceType="Unspecified" requireAccess="Execute". I also use verb="*" that shouldn't make a difference but might be worth a try.
Also note I do not have accessPolicy="Read, Execute, Script" attribute in the handlers section. I also do not remove WebDAV.
<system.webServer>
<handlers>
<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>
</system.webServer>

Actually removing WebDAV from my server caused the application to return a 503 Service Unavailable Error message, so I re-installed it.
I was able to fix this by disabling WebDAV for the individual application pool, this stopped the 'bad module' error.
Disable WebDAV for Individual App Pool:
- Click the affected web site in IIS
- Find
WebDAV Authoring Toolsin the list - Click to open it
- Click
Disable WebDAVin the top right.
Ta daaaa!
This link is where I found the instructions but it's not very clear.
For myself it wasn't enough to do everything @Luke was doing. I had to also go into my Programs and Features and and under Internet Information Services > World Wide Web Services > Common HTTP Features turn off WebDAV Publishing
That then fixed it for me.
