Dell DX6004S DX Object Storage SCSP Proxy Overview - Page 7

Syntax /_proxy/remote/uuid-or-name Description If the object exists in the local cluster the information is returned. Otherwise, the request is sent to each remote cluster in random order. If no cluster is able to locate the data, the error response from the local server is returned. remote is valid only for remote INFO requests and results in an error if used with any other method. remote causes a request for an object to be sent, referenced by UUID or by name, to a remote cluster. The information is returned from the first cluster that has the object. If the object cannot be found in any of the remote clusters, the error response that was received from the first remote cluster tried is returned. Note Support for remote proxy requests without the _proxy/ prefix is deprecated in this release and will be removed altogether in a future release. 1.2.1. Examples of using /_proxy Syntax As the following examples show, you must separate the URI from the domain specification using the slash character (/). In all cases, except where noted, the domain name must be passed as the Host in the request. Examples follow: • AggregateInfo of domain on either a local or remote cluster Local cluster: GET /_proxy/uuid?indirect=HEAD Remote cluster: GET /_proxy/cluster-name/uuid?indirect=HEAD For more information about AggregateInfo, see Section 1.2.3, "Remote Aggregate Info". • HEAD of a domain on either a remote or any cluster Remote cluster: HEAD /_proxy/remote?domain=domain-name Any cluster: HEAD /_proxy/any?domain=domain-name Note The domain= query argument is required whenever you perform an operation (in this case, HEAD) on a domain. • POST of an unnamed object to the default cluster domain POST /_proxy/cluster-name/ Copyright © 2010 Caringo, Inc.
