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

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 The idea of a common request handling system and three controlling libraries is outdated; the threaded server now being the only sensible controlling library.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.
