#303 Broken URL to on-line documentation

[Anders Andersson]

On the website there is a link to the on-line documentation in HTML, and it leads to a broken page (Cloudflare says "Error 1001 Ray ID: 94c7d69aac43667a • 2025-06-08 10:52:11 UTC
DNS resolution error")

This is because it goes to "gnuplot.info" and not "www.gnuplot.info". Adding the "www" makes it work.

I also noticed the inline pictures are broken for me for the same reason. The URL to the images in the document http://www.gnuplot.info/docs_6.0/loc282.html are hardcoded as (for example) "http://gnuplot.info/demo_6.0/windrose.1.png" which fails to resolve.

All I know for sure is that access via the same URL works for other people. A similar or possibly the same probable was reported last year. To the extent that I understand the resolution of that report (which honestly I mostly do not) it had something to do with whether the user's access proceeded via IPv4 or IPv6. Here is a link to part of that discussion:

Whoa! A project without control of its domain sounds like a very dangerous situation, I hope it can be remedied but the thread is over a year old so maybe not. I am indeed using IPv6 so that may be part of the problem. If the DNS gives out different answers for IPv4 and IPv6 users, I would expect this behavior.
