Could you add an example of how to handle POST request or QUERYSTRING?

Whats is the way to use httpUpdateServer with std::unique_ptr server definition ??

One thing that works for me if you have the ability to use port other than 80 is to use different port for every server.

This works great! However if I power down the ESP and power it back up again it starts the process completely over again where i have to go through the process of connecting my phone setting up/selecting the SSID and entering in my password. How do you keep it from trying to run the set up ever time it's powered down and back up again.

Do you have a similar example running on ESP32?
