Remarks

This operation does not block. This overridable implementation of SendAsync method forwards the HTTP request to the inner handler to send to the server as an asynchronous operation.

The SendAsync method is mainly used by the system and not by applications. When this method is called, it calls the SendAsync method on the inner handler.
