Network and request-header rules reclassified 74.5% of browser-User-Agent requests on a Cloudflare Worker blog
↗
A blog author implemented deterministic network and request-header rules in a Cloudflare Worker to separate automated traffic from genuine browser requests without relying on JavaScript.
Treating browser User-Agents as evidence of human readers leads to inflated analytics, as demonstrated by a single mobile-classified client fetching 31 pages in one second. Implementing deterministic edge rules provides a more accurate account of traffic but cannot definitively establish human readership, as client identity and readership require different evidence.

Network and header rules moved 277 of 372 browser-User-Agent requests out of the Browsers category.
Comparing edge page views with a script counter revealed a discrepancy of 1,209 page events versus 113 page loads.
The classification exposed implementation mistakes, such as an HTML-acceptance check mishandling valid headers, which have been repaired.
