How to confirm push webservices

I have a web service on my server that pushes xml data to clients who communicate with it over the Internet.

  • In these cases, we have a call to receive confirmation from the client.
  • A specific case, for example, when the client received the data and before sending a confirmation if the communication channel drops.

    Example: In the case of software updates on clients over the Internet, how the server guarantees that everything will be processed normally.
