IIS7 returning 500 for status code 401 when asp.net mvc app writes it to the response

Our mvc application sets the response status code to 401 and sets TrySkipIisCustomErrors to true under some circumstances.

I can see from the IIS log that it is getting this status code:

2012-05-04 01:32:42 10.212.98.183 POST /v1.07/session - 80 - 10.24.22.26 curl/7.20.1+(i686-pc-cygwin)+libcurl/7.20.1+OpenSSL/0.9.8r+zlib/1.2.5+libidn/1.18+libssh2/1.2.5 401 0 0 48325

However the response I receive in the client is 500:

< HTTP/1.1 500 Internal Server Error
< Content-Type: text/html
< Server: Microsoft-IIS/7.0
< Date: Fri, 04 May 2012 02:31:18 GMT
< Content-Length: 75
<
* Connection #0 to host webserver left intact
* Closing connection #0
The page cannot be displayed because an internal server error has occurred.

I have tried various other settings in the web.config for the mvc application around httpErrors and customErrors, none of which seem to make a difference.

How can I configure IIS to return the actual response and not 500?

So after a lot more googling, I changed the applicationHost.config file to allow delegation of httpErrors and now I get the correct response back to the client.

I had to set the following from Deny to Allow:

<section name="httpErrors" overrideModeDefault="Allow" />

I tried to follow the instructions in the file to use a <location> tag:

<location path="" overrideMode="Allow">
  <system.webServer>
    <httpErrors />
  </system.webServer>
</location>

but this did not work. It would work if I specified the web site in the path, rather than all sites though, however, I want to allow it for all the sites on the web server.
