Load Balancer

If a load balancer is in place, traffic is split across multiple servers, which may differ in configuration, security, or vulnerabilities. It can expose inconsistencies, help bypass protections like WAFs, and reveal how resilient the system is under stress.

Load Balancer Detection Methods

Method	Checks	Possible Indication
DNS Loadbalancing	Checks for different IPs when resolving the domain	Multiple backend IPs (DNS round-robin)
HTTP [Server]	Looks for changes in the Server response header	Different web servers behind a load balancer
HTTP [Date]	Compares the Date header in each response	Servers have unsynchronized clocks (suggests multiple servers)
HTTP [Diff]	Compares the full content of responses	Different server states or versions (or dynamic content)
