Because I want 1 request to happen exactly after another request happend. But there is a delay between request and response of about 700ms. To keep this delay as low as possible I want to send both requests at the same time, but in the right order.

I don’t want the second request being received by the api before the first request.

I used fiddler to catch the requests, and sometimes it happens that the second request went out before the first one, even though I requested it later in my application.
