In core master (not 2.0), reflinks has been converted to using requests instead of urllib2/httplib.

The change is https://gerrit.wikimedia.org/r/#/c/264251/ , by a GCI participant.

As requests does not support FTP, reflinks no longer supports FTP links.

A new task has been created to investigate FTP support: https://phabricator.wikimedia.org/T124007

There was also a minor performance regression. Where previously only the first 1Mb of a URL was fetched, now the entire resource is fetched.
