Hi guys,
I'm working on a little project using nodeMCU and Lua but i'm pretty new to these sort of things and i can't find a solution to my problem.
The project is basically to do a first access on the server, receive a page of control where I have to press a button connected to my nodemcu and after clicking it and refreshing i can reach the index page i loaded on the device.
The problem that I'm encountering is that if someone already reached the index page, everyone that tries to connect to the server will also go directly to the index, surpassing completely the control page.
I tried some solutions but none of them have worked in the end, so I'm asking if there is any easy solution to this.
Here is my code, with what is working so far:
