What is the difference between WiFiServer, WebServer and AsyncWebServer

[GeorgeFlorian1]

Hello !
Like the title says, I would like to know the difference between those libraries because I most certainly need to use one of them for my project. Also I think I'll need HTTP Client library.

I'm trying to serve a webpage. The webpage contains a input field where the user will write a URL. The URL will return some values (for example 0 or 1). I will want to store those values and use them later (for example if it's 1 then light a led up).

I am most curious about how do I take values inputted by the user from the webpage to store and use them.
