I want to setup a CTAN mirror but didn't get far after reading https://www.ctan.org/mirrors/register/ . I'd like to post something like Idiots guide to setting up a CTAN mirror as a question on tex.stackexchange.com
An answer to my question would probably revolve around current web server practices best suited for such a mirror, and so potentially be off-topic. But since the main audience would be LaTeX users, this seems a more natural fit. The question would be answerable: I would know upon successfully setting up such a mirror that the answer given was right.
