Change HTTP redirect to temporary redirect #1
Description
Currently when visiting https://www.preflib.org/ the server responds with HTTP 301 (Moved Permanently). That status code tells clients and search engines that the resource has permanently moved and that URLs should be updated.
However, I believe you still intend for users to use https://www.preflib.org/ and be redirected to https://preflib.github.io/PrefLib-Jekyll. In that case a temporary redirect would be more appropriate, e.g. 302 Found or 307 Temporary Redirect.
This issue came up during checks by the CRAN repository on one of my R packages that uses datasets from PrefLib in examples - I had to ask for an exception, which creates extra work, so it would be great if you could change this (assuming I am correct that we are not expected to update our references and links to https://preflib.github.io/PrefLib-Jekyll). Thanks!
