Cache response to respond to request later about cpp-httplib HOT 1 CLOSED

Can I somehow cache the response object provided to my GET lambda, and send the response when the position is available?

No, we can't. You may be able to do it with a simple loop inside a handler. It will simply wait until a new position data becomes available, then prepare the body content and return.

Here is a pseudo code. (It may not work though...)

  svr.Get("/player_pos", [&](const Request & /*req*/, Response &res) {
    while (is_position_available == false) {
      std::this_thread::sleep_for(std::chrono::seconds(2));
    }
    
    auto json = ...; // get the position data and convert it to JSON text.
    
    res.set_content(json, "application/json");
  });

Hope it helps!
