Redirection of the ade4 web page

In the DESCRIPTION file of the ade4 package, we find 2 URLs:

URL: https://adeverse.github.io/ade4/, http://pbil.univ-lyon1.fr/ADE-4/

The GitHub URL of the adeverse organization: https://adeverse.github.io/ade4/ as well as the "historical" URL: https://pbil.univ-lyon1.fr/ADE-4/ which is in fact a redirection link to the GitHub URL. This redirection is done by a PHP script, without changing anything in the structure of the pbil.univ-lyon1.fr web server.

In the /www/htdocs/pbil/ directory of the pbil web server we find the ADE-4 directory, and an ade4 link which allows to keep the old URL active:

• drwxrwxr-x 7 www-data web 55 Jan 22 11:24 ADE-4
• lrwxrwxrwx 1 www-data web 5 Nov 22, 2010 ade4 -> ADE-4

In the /www/htdocs/pbil/ADE-4 directory, there are two PHP files which are symbolic links to the same ade4New.php file:

• lrwxrwxrwx 1 jthioulo bge 11 June 15, 2023 accueil.php -> ade4New.php
• lrwxrwxrwx 1 jthioulo bge 11 June 15, 2023 index.php -> ade4New.php

The ade4New.php file itself contains a single line of PHP code, which consists of a header that redirects the browser to the adeverse GitHub URL:

<?php header('Location: http://adeverse.github.io/ade4/'); ?>
