The error occurred on the ciao-lang download page:

http://ciao-lang.org/cgi-bin/download.cgi?url=/packages/1.14/13646/CiaoDE-1.14.2-13646.tar.gz&list=ciao-users

I just attempted again and cannot reproduce the error.�� It appears to work on both Windows and FreeBSD now.

After posting the message, I managed to find the github repo, which is much more convenient for my purposes. Perhaps it could be listed on the ciao-lang site?

Both the SWI prolog and Ciao Prolog are self-hosted -- ie. the web server is written in prolog AFAIK.��

Aside: I studied Common Lisp long before I learned about prolog.�� Advanced Lisp books always have a section devoted to prolog interpreters and logic programming (especially Norvig's Paradigms in Artificial Intelligence aka PAIP or Paul Graham's On Lisp). This inspired me to study prolog and logic programming directly.�� Now I enjoy prolog as much as I do CL. But I find the various prolog projects with much better documentation.��

Will you provide the URL to the site/page that gave the error?

Is that typical behavior of mainstream web technology (e.g., a LAMP-stack, framework-based web-app (where the LAMP "P" might be PHP, Python, or Perl (I noticed the Lisp in your address (hello))))?

The SWI-Prolog site, for example, seems somewhat atypical : <http://www.swi-prolog.org/dogfood.html>

Is the Ciao-Prolog site[1] similarly atypical?
