IIS intercepting WebApi call

I have a WebApi service that is designed to upload a file via a POST message and the url would look something like http://website:port/api/files/file.png which works fine when I run against cassini but when I run the same thing against IIS my web api isn't called and I get a 404.  What I believe is happening is that IIS is seeing the URL and assuming that it should be mapped to a file that is on the server itself. 

Here is the route that I have set up:

RouteTable.Routes.Add(new ServiceRoute("api/files", this.apiFactory, typeof(FilesService)));

Here is the WebApi method signature:

[WebInvoke(UriTemplate = "{filename}", Method = "POST")]
public HttpResponseMessage Upload(string filename, HttpRequestMessage request)

What is the trick to getting IIS to ignore the url and just pass it down to the routing system?

What OS (aka, what version of IIS)?

Have you tried this?

RouteTable.Routes.RouteExistingFiles = true;

I just tried it but it didn't make any difference.

At the moment I am just replacing the . with a ~ at the client and then switch it back when I hit the server.  Though I am hoping this will be temporary.

Why isn't "filename" a part of the request body that's being posted to "/api/files"?

Mostly because I want the GET and POST methods to seem natural and consistent.

i.e. GET /api/files/filename.png would return the file.

While I realize there are work arounds I would prefer to make it do what I want if that is at all possible.
