Is an entity body allowed for an HTTP DELETE request?

Question

When issuing an HTTP DELETE request, the request URI should completely identify the resource to delete. However, is it allowable to add extra meta-data as part of the entity

Answer 1

It seems ElasticSearch uses this: https://www.elastic.co/guide/en/elasticsearch/reference/5.x/search-request-scroll.html#_clear_scroll_api

Which means Netty support this.

Like mentionned in comments it may not be the case anymore
