edgeResponseBytes and cacheResponseBytes discrepancy

Last updated Jun 30, 2026Copy as MarkdownView as MarkdownAgent setup

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.
