Did you know that HTTP traffic is the data flow between a client (like a web browser) and a server over the internet, using the HTTP protocol? This protocol defines how data is formatted and transmitted primarily between web servers and clients.
Whenever you request a webpage or any data from a web server, your client sends an HTTP request to the server, which then responds with an HTTP response containing the requested data. This communication between the client and server constitutes HTTP traffic.
To ensure the security and performance of web applications and websites, HTTP traffic can be analyzed using various tools like network sniffers, web application firewalls, and HTTP proxies. These tools can help identify potential security threats, performance issues, and other problems related to web applications and websites.
