title: edgeResponseBytes and cacheResponseBytes discrepancy
description: In HTTP request logs, cacheResponseBytes reflects the uncompressed response size from cache or origin. edgeResponseBytes reflects the final compressed response size sent to the client. Because Cloudflare applies compression (gzip, Brotli) before delivering to the client, edgeResponseBytes is typically smaller than cacheResponseBytes.
