What your child can do at the end
Read an HTTP request and name every header you see
The brief
HTTP is text. A request is a verb, a path, a version and a list of headers. A response is a number, a list of headers and a body. Everything the web does is built on that. In this lab you read the real request and response for every load, watch the headers change when you switch on compression or caching, and see what a 304, a 404 and a 500 actually look like on the wire.

How it is assessed
3 graded challenges inside the lab, and 8 questions at the end that check the idea rather than the clicks. Every attempt is saved, so a retry after a mistake counts as the learning it is.
