Cache, headers, static assets, and diagnostic behavior
Lab 4 is dedicated to testing and explaining Cloudflare cache behavior, response headers, static asset delivery, and diagnostic workflows. This content is intentionally isolated to this lab page.
Demonstrable content
Use these commands to test cache and header behavior:
curl -I https://www.ybarra-cflab.com/ curl -I https://www.ybarra-cflab.com/static/logo.txt curl -I https://www.ybarra-cflab.com/health/ curl -I https://www.ybarra-cflab.com/headers/
What was completed
- Created a dedicated cache and diagnostics lab page.
- Validated static asset delivery using
/static/logo.txt. - Separated Lab 4-specific content from the landing, app, and previous lab pages.
- Added utility pages for health, diagnostics, and header inspection.
- Removed malformed static asset references such as trailing backslashes.
Technical summary
We isolated cache and diagnostic testing into a dedicated Lab 4 page. This page provides commands and links for validating static asset delivery, response headers, cache-related behavior, and utility routes. By keeping this content contained, the rest of the site remains clean and focused on project navigation instead of being polluted with Lab 4-specific testing artifacts.
Customer-facing summary
We created a dedicated troubleshooting area for testing how Cloudflare serves and caches the website. This keeps the main site clean while still giving us a clear place to prove that assets, headers, and diagnostic pages are working correctly.
Static asset validation
The correct static asset URL is:
https://www.ybarra-cflab.com/static/logo.txt
