Which tool is used for load-balancing detection by header analysis rather than broad web technology discovery?

• A. WhatWeb
• B. lbd
• C. Vega
• D. Gobuster

Answer: (B)

Detecting a load balancer by header analysis relies on recognizing signatures that proxies insert into HTTP responses. The tool designed for this purpose, lbd, specifically analyzes headers such as Via, X-Forwarded-For, X-Forwarded-Proto, X-Cache, and related fields to determine that a load balancer or reverse proxy sits in front of the application and often to identify the vendor or type. This targeted approach is different from broad web technology fingerprinting or general vulnerability scanning. WhatWeb aims to fingerprint a wide range of technologies used by a site, Gobuster is for directory or file discovery, and Vega is a web vulnerability scanner. They don’t focus on identifying load balancers through header cues. So lbd is the best fit for load-balancing detection via header analysis because it is built to interpret those header signals and report the presence and sometimes the exact type of intermediary performing the load balancing.
