HTTP Framework

The result of HTTP handlers are automatically converted into HTTP responses. By default, they are converted to JSON, and returned with a content-type based on their type: records, dictionaries and lists are given the content-type "application/json; charset=utf-8", all other types are given the content-type "text/plain; charset=utf-8".

We recogize this is a poor choice, and future versions of the HTTP stack will have better default behaviour.

The HTTP:: module provides functions to create responses to external HTTP calls. Each response function, such as Http::response, creates a response value; a response value returned by the handler will be sent as a response to the client.


The live value beneath the handler will show the return value.
