IIS does not serve .dat files

Question

I have an ASP MVC web application that uses a plugin to load images and points for a 3D application.

When debugging with the Visual Studio development server, the images and dots work fine ...

Second image: same url, but iis.png

When working in IIS 7, although .Dat point files do not serve and do not create 404.

I noticed that caching is marked as private in the violinist, but I don't know what that means. Can anyone help?

Greetings

For an Azure web application, the following changes to web.config did the trick, thanks for the tip like Mime:

<system.webServer>
  <staticContent>
    <remove fileExtension=".dat" />
    <mimeMap fileExtension=".dat" mimeType="application/octet-stream" />
  </staticContent>
</system.webServer>
