Disclosed are methods, systems, and computer programs for facilitating communication between a client application and a server application. A client application initiates an asynchronous communication with the server application by sending a request via a communication manager. The communication manager sends the request synchronously to the server application. Responsive to the communication manager not having received a final response from the server application, the communication manager responds to the client application that the sending the request was unsuccessful. Responsive to the communication manager having received a final response from the server application, the communication manager retains the response from the server application and responds to the client application that the sending a request was successful. The client application requests a final response from the communication manager and the communication manager provides the previously retained response.
