## Article

### Why do we need this [AsyncWebServer_ESP32_SC_W5500 library](https://github.com/khoih-prog/AsyncWebServer_ESP32_SC_W5500)

#### Features

This library is based on, modified from:

1. [Hristo Gochkov's ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer)

to apply the better and faster **asynchronous** feature of the **powerful** [ESPAsyncWebServer Library](https://github.com/me-no-dev/ESPAsyncWebServer) into **(ESP32_S2/S3/C3 + LwIP W5500)**.

#### Why Async is better

- Using asynchronous network means that you can handle **more than one connection at the same time**

- **You are called once the request is ready and parsed**

- 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

- **Speed is OMG**

- **Easy to use API, HTTP Basic and Digest MD5 Authentication (default), ChunkedResponse**

- Easily extensible to handle **any type of content**

- Supports Continue 100

- **Async WebSocket plugin offering different locations without extra servers or ports**

- Async EventSource (Server-Sent Events) plugin to send events to the browser

- URL Rewrite plugin for conditional and permanent url rewrites

- ServeStatic plugin that supports cache, Last-Modified, default index and more

- Simple template processing engine to handle templates

#### Currently supported Boards

1. **ESP32_S3 boards** using `LwIP W5500 Ethernet`

2. **ESP32_S2 boards** using `LwIP W5500 Ethernet`

3. **ESP32_C3 boards** using `LwIP W5500 Ethernet`
