.. _discoverability:

Discoverability
===============

Swift will by default provide clients with an interface providing details
about the installation. Unless disabled (i.e ``expose_info=false`` in
:ref:`proxy-server-config`), a GET request to ``/info`` will return configuration
data in JSON format.  An example response::

    {"swift": {"version": "1.11.0"}, "staticweb": {}, "tempurl": {}}

This would signify to the client that swift version 1.11.0 is running and that
staticweb and tempurl are available in this installation.

There may be administrator-only information available via ``/info``. To
retrieve it, one must use an HMAC-signed request, similar to TempURL.
The signature may be produced like so::

    swift-temp-url GET 3600 /info secret 2>/dev/null | sed s/temp_url/swiftinfo/g

DLO support centers around a user specified filter that matches
segments and concatenates them together in object listing order. Please see
