Fixing empty responses from Cloudflare Workers Sites

Read Original

This technical article details a debugging case where a Cloudflare Workers Sites deployment intermittently returned empty 200 responses, breaking page rendering. The author identifies the root cause as the automatic 'Last-Modified' header triggering faulty conditional GET requests, and provides the code fix of deleting this header in the worker's event handler.
