How Attackers Sneak in Hidden Requests and What You Can Do About It

In today’s digital landscape, web security is a crucial concern for both developers and organizations. One of the more sophisticated and lesser-known vulnerabilities that can wreak havoc on web applications is HTTP Request Smuggling. While it may sound complex, understanding this vulnerability is essential for ensuring the security of your applications. In this article, we’ll break down HTTP Request Smuggling, explain how it works, and discuss ways to prevent it. Whether you’re a beginner or have some experience in web security, this guide will provide valuable insights.

HTTP Request Smuggling is a type of attack where a malicious user exploits the inconsistencies between how different web servers or proxies interpret HTTP requests.
