httpreserve

A tool to check the status of a weblink and also see whether it is archived in the Internet Archive.

Try it out here httpreserve.info

Default Server

The library comes with a default server mode that can be configured for POST and GET requests. POST by default. Default port is :2040 but this can also be selected at runtime.

The default server can also be stood up as a web service. The API is documented below.

Client

The httpreserve linstat client is a separate application offering simple access to httpreserve functionality through the command line. See linkstat

The client application is a work in progress. Stay tuned for more information about its capabilities.

API

Primary entry point when the server is running:

http://{httpreserve-ip-address}:{port}/httpreserve

or

http://{httpreserve-ip-address}:{port}/save

GET example:

• Return JSON struct with information about the service you requested:

  http://{httpreserve-ip-address}:{port}/httpreserve?url=http://www.google.com&filename=filename.txt

• Manage a save request to the internet archive and return HTTPreserve struct:

  http://{httpreserve-ip-address}:{port}/save?url=http://www.google.com&filename=filename.txt

POST example:

Same access point, but encode url and filename in a <i>application/x-www-form-urlencoded</i> form.

Robust links and Persistent Web Identifiers

HTTPreserve tries to promote the use of emerging standards such as Mementoweb's Robust Links and the Royal Danish Library's Persistent Web-Identifiers (PWIDs).

More information about those can be found at the links below:
