# remote_url_prefix
<note>
  This option is only used by the [Reindex action](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/elasticsearch/curator/reindex) when performing a remote reindex operation.
</note>

This should be a single value or left empty.
```yaml
actions:
  1:
    description: "Reindex index1 into index2"
    action: reindex
    options:
      wait_interval: 9
      max_wait: -1
      remote_url_prefix: my_prefix
      request_body:
        source:
          remote:
            host: <OTHER_HOST_URL>:9200
          index: index1
        dest:
          index: index2
    filters:
    - filtertype: none
```

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/](http://example.com/elasticsearch/) as opposed to [http://localhost:9200](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.
