Add a custom response header in ApiController

Question

Until now, I had a GET method that looked like the following:

protected override async Task GetAll(QueryData query)
{

You can explicitly add custom headers in a method like so:

[HttpGet]
[Route("home/students")]
public HttpResponseMessage GetStudents()
{
       // Get students from Database

       // Create the response
        var response = Request.CreateResponse(HttpStatusCode.OK, studends);

        // Set headers for paging
        response.Headers.Add("X-Students-Total-Count", studends.Count());

       return response;
}
