Julian Reschke commented on HTTPCORE-380:
-----------------------------------------
"A request method is considered "idempotent" if the intended effect on the
server of multiple identical requests with that method is the same as the
effect for a single such request. Of the request methods defined by this
specification, PUT, DELETE, and safe request methods are idempotent."
-- <https://greenbytes.de/tech/webdav/rfc7231.html#idempotent.methods>
So how exactly is DELETE-with-body non-idempotent? (no matter how bad the idea
might be in the first place...)

> Hi All,
> I have created a fix to support HTTP DELETEs with entity bodies. In HTTP
> Core, the HttpRequest object (BasicHttpRequest or
> BasicHttpEntityEnclosingRequest) is made by looking at the HTTP method. But
> sometimes an API could accept HTTP Deletes with payloads for example [1]. To
> support this I have introduced a new type of HTTP requests
> "HttpEntityPossibleEnclosingRequest". By calling the "getFinalHttpRequest"
> method in this class, the proper HTTP request object can be made, i.e.
> HttpRequest or HttpEntityEnclosingRequest. The logic is if the
> HttpEntityPossibleEnclosingRequest has the CONTENT_LENGTH header, an
> HttpEntityEnclosingRequest is made and an HttpRequest is made otherwise.
> Note. the spec does not prohibit an HTTP Delete having a payload [2] [3].
