In each instalation, to user can use reflinks script, have to have this file in main folder.. I support idea for creating web server, with which reflinks.py will interact by API. Than user(s) will not need to every time download this file.
@Zoranzoki21, @zhuyifei1999, @Cyberpower678: reflinks.py is a Python script, which goes through bare links in a wiki page (pages) and finds out more details (page title, mime type). This script uses a pre-generated text file containing 404 links (gathered from wiki pages) to avoid marking temporarily unaccessible links as dead links. The text file could be downloaded from script-author's webpage, but it is old and unmaintained there and contains only enwiki articles. It can also be newly created by yourself using Python script weblinkchecker.py, but it takes a week to create this list (in order to eliminate temporarily unaccessible links). Currently we are looking for a better solution.
