TreKing's point is, it's safer to do this asynchronously. There are so many things that can go wrong with an HTTP request, you don't want to have your users waiting for it to return. Especially if there's nothing being displayed to the user, they don't know or care about the response from the server.
Instead, create a service to make the request instead. It will run in the background and still guarantee the request will be made with as much certainty as doing it within your Action. You can even add some retries within the exception handling in case the server is unreachable. K.
