How to useSession Variable in HTTP

Approach 2: Using File based Counter

In this approach, we are using the session variables to count and store details of each HTTP request, which includes the request method, time, and the IP address of the client. We are displaying the total number of requests and if there is more than one request then the list of detailed information for each of the requests is shown in the list bullet manner.

Example: In the below example, we will find the total number of HTTP requests in PHP using session variables.

PHP

<?php 
session_start(); 
  
// Increasing the request count 
if (!isset($_SESSION["request_count"])) { 
    $_SESSION["request_count"] = 1; 
} else { 
    $_SESSION["request_count"]++; 
} 
  
// Storing details about the current request 
$requestDetails = [ 
    "method" => $_SERVER["REQUEST_METHOD"], 
    "timestamp" => date("Y-m-d H:i:s"), 
    "ip" => $_SERVER["REMOTE_ADDR"], 
]; 
if (!isset($_SESSION["request_details"])) { 
    $_SESSION["request_details"] = []; 
} 
$_SESSION["request_details"][] = $requestDetails; 
  
// Displaying the total number of  
// requests and request details 
echo "Total HTTP Requests: {$_SESSION["request_count"]}<br>"; 
if ($_SESSION["request_count"] > 1) { 
    echo "<h3>Request Details:</h3>"; 
    echo "<ul>"; 
    foreach ($_SESSION["request_details"] as $request) { 
        echo "<li>{$request["method"]} request from {$request["ip"]} 
          at {$request["timestamp"]}</li>"; 
    } 
    echo "</ul>"; 
} 
?>

How to find the total number of HTTP requests ?

In this article, we will find the total number of HTTP requests through various approaches and methods like implementing server-side tracking by using PHP session variables or by analyzing the server logs to count and aggregate the incoming requests to the web application. By finding the total count of HTTP requests we can understand the web application metrics to optimize the application.

There are two approaches through which we can find the total number of HTTP requests.
