Hurl (via) Hurl is “a command line tool that runs HTTP requests defined in a simple plain text format”—written in Rust on top of curl, it lets you run HTTP requests and then execute assertions against the response, defined using JSONPath or XPath for HTML. It can even assert that responses were returned within a specified duration. # 22nd November 2021, 3:32 am
New HTTP standards for caching on the modern web (via) Cache-Status is a new HTTP header (RFC from August 2021) designed to provide better debugging information about which caches were involved in serving a request—“Cache-Status: Nginx; hit, Cloudflare; fwd=stale; fwd-status=304; collapsed; ttl=300” for example indicates that Nginx served a cache hit, then Cloudflare had a stale cached version so it revalidated from Nginx, got a 304 not modified, collapsed multiple requests (dogpile prevention) and plans to serve the new cached value for the next five minutes. Also described is $Target-Cache-Control: which allows different CDNs to respond to different headers and is already supported by Cloudflare and Akamai (Cloudflare-CDN-Cache-Control: and Akamai-Cache-Control:). # 21st October 2021, 10:40 pm
