Custom header not found in HttpContext.Current.Request.Header array

Question

I add a custom header to each of my calls made from an Angular service to pass a system Id to my application

$http.defaults.headers.common["SystemId"] = "1";

When using Fiddler I can see that the custom header is added

enter image description here

On the server side I'm trying to retrieve this header from a user defined C# class by doing the following

if (HttpContext.Current != null)
{
    systemIdHeader = HttpContext.Current.Request.Headers["SystemId"];                                
}

The HttpContext.Current object is set but the Headers array is empty. Is there any reason why this header will go missing?

Is whole collection empty or maybe SystemId is missing?

Ok I found the problem. I'm posting to an oAuth token endpoint which is making use of the OAuthGrantResourceOwnerCredentialsContext, so I had to use

_oAuthGrantResourceOwnerCredentialsContext.Request.Headers["SystemId"];

instead of

HttpContext.Current.Request.Headers["SystemId"];
