SWI-Prolog HTTP support library
This directory provides the SWI-Prolog libraries for accessing and providing HTTP services.
Client library
The main client library is library(http/http_open), which can open
both HTTP and HTTPS connections and handle all request methods.
Server library
The main server libraris are
library(http/thread_httpd)implements the serverlibrary(http/http_dispatch)implements binding locations predicateslibrary(http/http_unix_daemon)implements integration in various Unix server managers and in general provides a suitable entry point for HTTP servers on Unix.library(http/html_write)implements generating HTMLlibrary(http/http_json)implements reading and writing JSON documents.
For simplicity, you can use library(http/http_server), which
combines the typical HTTP libraries that most servers need. The
idea of a common request handling system and three controlling
libraries is outdated; the threaded server now being the only sensible
controlling library.
Requirements
This library uses functionality from the ssl package to support HTTPS,
the sgml package to read XML/HTML and the clib package for various
extensions.
