Swift will by default provide clients with an interface providing details about the installation. Unless disabled (i.e expose_info=false in Proxy Server Configuration), 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 the DLO docs for Dynamic Large Objects further details.
Please see the SLO docs for Static Large Objects further details.
