In some cases you may be obliged to connect to a remote Elasticsearch cluster through a proxy of some kind. There may be a URL prefix before the API URI items, e.g. http://example.com/elasticsearch/ as opposed to http://localhost:9200. In such a case, set the remote_url_prefix to the appropriate value, elasticsearch in this example.

The default is an empty string.
