Extension summary
You spend lots of time to optimize your infrastructure to make sure you servers respond with correct cache headers?
You use a CDN to speed-up your content delivery but you don't know if it is really working?
This extension for the developer tools gives you an overview about all relevant request headers (method, if-modified-since, if-none-match) and response headers (cache-control, pragma, last-modified, etag) in one single table.
It also detects if elements are fetched through a CDN and shows you the cache status of the CDN (currently only Cloudflare is supported).
