Custom headers ASP.net MVC

Question

I'm trying to serve WebDav requests to create a CalDav server so that users can access our calendar function easily on any device of their choosing.

The problem is in trying to serve any custom headers. I've written a custom ActionResult that sets up any result easily in the right way. Upon a OPTIONS request, which gets recognized, it adds:

response.AppendHeader("Allow", "OPTIONS, PROPFIND, HEAD, GET, REPORT, PROPPATCH, PUT, DELETE, POST");

When I look into the request that the end-user receives the following header appears:

Allow: OPTIONS, TRACE, GET, HEAD, POST

When I then try to do a request with the custom header PROPFIND it simply returns a 404 error. I tried googling but there is not a lot around about this stuff. It's probably something I have to enable or disable.

Answer 1

I had to remove the WebDavModule and WebDav handler in the web config. After I had done that it worked perfectly.

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