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)
{
              


        

Answer 1

What you need is:

public async Task Get() 
{ 
    var response = Request.CreateResponse();
    response.Headers.Add("Lorem", "ipsum");

    return base.ResponseMessage(response); 
}

I hope this answers your question.
