I saw a mention of the IndieWeb idea of notifying the Internet Archive when a new page is posted.
Trigger an Archive
You can tell archive.org to crawl and archive a specific URL immediately.
$ curl -I -H "Accept: application/json" http://web.archive.org/save/{url to archive} | grep Content-Location
and you'll get a response like:
Content-Location: /web/20160715203015/http://indieweb.org
The response includes the path to the archived page on web.archive.org. Append this path to http://web.archive.org to build the final URL for the archived page.
I use Jekyll for this site, and I manage building and publishing with a Makefile. I added this trigger to it, and now the publish part looks like:
Now, this just tells the Internet Archive to get my site’s home page. It doesn’t specify which pages have been added and/or updated. That would require keeping track of all the site’s content and checking for differences every time I publish, which is certainly possible, but would require making a new plugin. Adding one line to the Makefile is far easier and gets 95% of the work done.
