That doesn't seem to be the case:

  curl -v http://www.milliondollarhomepage.com/index_files/widgets.js

returns an HTTP 200 (not a 301/302). Additionally, the comment says:

  /*

Note the dates. It was archived on Aug 6, 2015 and retrieved just 18 days later on Aug 24, 2015. Given it's 2017, there's no way this file is being served directly from archive.org's servers.

The '/index_files/' bit seems to imply someone went to the internet archive, pulled up milliondollarhomepage, and then in a Browser, did 'Save As Webpage Complete' which saves the main page (in this case index.htm) and all its assets in a sub folder called 'index_files'.

They then just copied it all as-is back into some web hosting.
