[ESP32][ESP-IDF][HTTPD-Server] One client at a time

[ajay_ambaliya]

What I need?
- I wanted to allow only one client at a time. i.e.. If I open http://ip:port in browser so client connected to ESP now no more browser can connect to esp until running tab close or browser close.
- Here is i have attached code of sample server.

Code: Select all

#include <stdio.h>
#include "esp_err.h"
#include "esp_event.h"
#include "esp_http_server.h"

static esp_err_t hello_get_handler(httpd_req_t *req) {
    const char* response = "Hello, ESP32 HTTP Server!";
    httpd_resp_send(req, response, strlen(response));
    return ESP_OK;
}

void app_main(void) {
    httpd_config_t config = HTTPD_DEFAULT_CONFIG();
    httpd_handle_t server = NULL;

    // Start the server
    if (httpd_start(&server, &config) == ESP_OK) {
        // Set URI handlers
        httpd_uri_t hello = {
            .uri       = "/hello",
            .method    = HTTP_GET,
            .handler   = hello_get_handler,
            .user_ctx  = NULL
        };
        httpd_register_uri_handler(server, &hello);
    }
}
