(English is not my native language)
(I can’t insert more than two links because of restrictions for new users)
I work with script WebCite Archive — https: //greasyfork.org/ru/scripts/19361-webcite-archive-vivre — which archives on WebCite — http:// webcitation.org/ — all links in my HTML documents. It seems to me that the plugin which will automatically replace dead links — https: //en.wikipedia.org/wiki/Wikipedia:Link_rot — in files will be very useful.
I think that it can work so. User starts a plugin. Plugin check all links in documents of the user. The user can start a plugin at any time when he wants. If, for example, in a month the link remains dead, the plug-in replaces it with the archival copy of the link from WebCite. For example: https://en.wikipedia.org/wiki/Wikipedia:Link_rot replace to http://www.webcitation.org/query?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FWikipedia%3ALink_rot&date=2016-05-09. If the link is not saved in WebCite, a plug-in will do of nothing.
Thanks.
