ENABLE LOGGING OF THE X-FORWARDED-FOR HEADER
LOGGING OF THE X-FORWARDED-FOR HEADER FOR BETTER SECURITY & ATTACK MITIGATION In enterprise Adobe Experience Manager (AEM) environments, security and visibility are crucial, especially when responding to suspicious or malicious traffic patterns such as DoS or DDoS attacks. One common challenge DevOps teams face during such incidents is tracing the actual end-user IP address — especially when traffic is routed through load balancers, proxies, or CDNs. This is where the X-Forwarded-For (XFF) HTTP header becomes vital. In this blog, we’ll explore how to properly log the X-Forwarded-For header in AEM Dispatcher (both Apache and IIS) and configure debugging for better traceability. Why X-Forwarded-For Matters The X-Forwarded-For header is widely used to preserve the original client IP address when requests pass through a proxy or load balancer. Without logging this header, access logs might only show internal IPs of the proxy, which is not helpful when analyzing or block...
