![]() When you send the response, you are immediately ready to handle other connections while the server is taking care of sending the response in the background.You are called once the request is ready and parsed.Using an asynchronous means server can handle more than one connection at the same time from clients. ![]() Using an Async web server has many benefits as discussed on the official GitHub page of this library: In this tutorial, we will use the ESPAsyncWebServer library to build Async Web Server with ESP32 and Arduino IDE. In other words, in an asynchronous server, client HTTP requests do not block each other and get executed concurrently. It has a worker process that accepts HTTP requests from all clients and processes client requests by using event-driven efficient loops. On the contrary, Asynchronous servers do not create a separate thread for each client request. But it may induce blocking problems when a server is waiting for the process to release the resources. In the case of traditional thread based servers, there is a dedicated separate thread for each client to serve that particular client. loop() function Asynchronous Web Server Introduction What is Asynchronous Web Server?Īn asynchronous web server is a server that can handle XMLHttpRequests requests in a scalable fashion. ![]()
