FIELD NOTES

Notes from the actual work, written when it happens.

Field Notes are shorter and more frequent than TRACE: a bug found, a fix verified, a decision explained — with the actual commands, headers, or code, not a summary of them.

Two Subdomains, Same Host, Different Cache Headers

Identical .htaccess · identical origin · 7-day cache on one, 1-year on the other

Two subdomains on the same hosting account, same CDN product, identical .htaccess Cache-Control rules — and browsers were receiving two completely different cache lifetimes. A step-by-step trace of how I isolated the layer responsible, and the single directive that fixed it without disabling the CDN or migrating providers.
