The Internet Archive is a non-profit organization that is building a digital library, including archival copy of much of the public web.

How to

Trigger an Archive

You can tell archive.org to crawl and archive a specific URL immediately.

$ curl [[curl -I|-I]] [[curl -H|-H]] "Accept: application/json" https://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 https://web.archive.org to build the final URL for the archived page.

Trigger Archive in PHP

PHP snippet to call the curl_exec() function with appropriate options/params to trigger an archive:

$options = 
array(CURLOPT_URL => ('https://web.archive.org/save/' . $url_to_save),
      CURLOPT_HEADER => true,
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_HTTPHEADER => array('Accept: application/json'),
      CURLOPT_USERAGENT => "YOUR_CMS_NAME_HERE");
$ch = curl_init();
curl_setopt_array($ch, $options);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

You can then check $info['http_code'] for a numeric HTTP return code to see if there was an error (e.g. >= 400) and take action accordingly.

Trigger Archive in Python (with requests)

This method requires the 'requests' Python library.

pip install requests
import requests

# fire and forget archive.org call
try:
    verify = requests.get(
        '%s%s' % ('https://web.archive.org/save/', target),
        allow_redirects=False,
        timeout=30,
    )
except:
    pass

Trigger Archive in Ruby

This is a Ruby method that triggers archiving by the Internet Archive for a given URL. It returns the URL that you can visit to see the archived page. It uses the rest-client Ruby gem to make a GET request.

require 'rest-client'

def web_archive(url)
  archive_request_response = RestClient.get("https://web.archive.org/save/#{url}")
  "https://web.archive.org" + archive_request_response.headers[:content_location]
end

Known

(new!) There is a Known plugin to auto-archive your posts and edits to your posts, as well as pages that you bookmark:

Limitation(?)

WordPress

There is a useful little plugin Post Archival in the Internet Archive which will not only archive the user's post, but will also archive all the links within the post.
