For more examples of SWI-Prolog HTTP servers see the GitHub repository

These are simple, easy to understand, practical at the same time and blessed with Anne’s touch.

Some also use [library(pengines)](https://www.swi-prolog.org/pldoc/doc_for?object=section(%27packages/pengines.html%27)) which is nice if you need examples for them.

Anne’s tutorial is a bit out of date – amongst other things, it doesn’t use `library(http/http_server)`.

@jan Perhaps add a pointer to [GitHub - kamahen/swipl-server-js-client: Sample SWI-Prolog server with JavaScript client](https://github.com/kamahen/swipl-server-js-client) and the items that @EricGT mentioned?  
(I wrote swipl-server-js-client to clarify things to myself that I couldn’t easily figure out from Anne’s tutorial.)

Hi Peter. I met difficulties to use your swipl-server on my personal blog because of two reasons

1. I do not know how `localhost:9999` (for example) can be translate for a website with apache2
2. I did not succeed with https and Prolog, in spite of the documentation.

Not so easy, … for me. ☹
