Discoverability

Swift will by default provide clients with an interface providing details about the installation. Unless disabled (i.e expose_info=false in 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
