About CDN Headers & Cookies

CDN Headers & Cookies is a developer-focused browser extension that helps you understand what happens between your browser, the origin, and the CDN serving a page. Features: 1. Inspect request headers for requests made by the current page. 2. Add, edit, and remove custom request headers globally or for specific hosts. 3. Inspect response headers and CDN-specific debug headers. 4. Automatically detect supported CDNs. 5. Detect CDN cache status, including cache hits, misses, and revalidations. 6. Request additional CDN debug information when supported. 7. Follow and inspect complete redirect chains. 8. View, add, edit, and remove cookies for the current domain. 9. Search and sort headers and cookies. 10. Copy or export data as JSON, CSV, plain text, or cURL commands. 11. Use the extension from either the popup or browser Side Panel. 12. Light and dark theme support. Built for developers, CDN engineers, SREs, performance engineers, and anyone who needs a clear view of HTTP and CDN behavior directly from the browser.
