# Async Requests Handlers HTTPD Server Example
|
|
|
|
The Example demonstrates how to handle multiple long running simultaneous requests
|
|
within the HTTPD server. It has the following URIs:
|
|
|
|
1. URI \long for demonstrating async requests running in the background
|
|
2. URI \quick for demonstrating that quick requests are still responsive
|
|
2. URI \ index page
|
|
|
|
## How to use example
|
|
|
|
### Hardware Required
|
|
|
|
* An ESP-Dev-Board (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
|
|
* A USB cable for power supply and programming
|
|
|
|
### Configure the project
|
|
|
|
```
|
|
idf.py menuconfig
|
|
```
|
|
* Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
|
|
|
|
### Build and Flash
|
|
|
|
Build the project and flash it to the board, then run monitor tool to view serial output:
|
|
|
|
```
|
|
idf.py -p PORT flash monitor
|
|
```
|
|
|
|
(Replace PORT with the name of the serial port to use.)
|
|
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
|
|
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
