@ResponseBody

		RequestMethod.PUT, RequestMethod.PATCH, RequestMethod.DELETE, RequestMethod.OPTIONS })
public Mono<Void> endpointProxy(@PathVariable("instanceId") String instanceId, HttpServletRequest servletRequest,
		HttpServletResponse servletResponse) throws IOException {
	ServerHttpRequest request = new ServletServerHttpRequest(servletRequest);
	String endpointLocalPath = this.getEndpointLocalPath(this.adminContextPath + INSTANCE_MAPPED_PATH,
			servletRequest);
	URI uri = UriComponentsBuilder.fromPath(endpointLocalPath).query(request.getURI().getRawQuery()).build(true)
			.toUri();

	// We need to explicitly block until the headers are recieved and write them
	// before the async dispatch.
	// otherwise the FrameworkServlet will add wrong Allow header for OPTIONS request
	Flux<DataBuffer> requestBody = DataBufferUtils.readInputStream(request::getBody, this.bufferFactory, 4096);
	ClientResponse clientResponse = this.instanceWebProxy
			.forward(this.registry.getInstance(InstanceId.of(instanceId)), uri, request.getMethod(),
					this.httpHeadersFilter.filterHeaders(request.getHeaders()),
					BodyInserters.fromDataBuffers(requestBody))

	ServerHttpResponse response = new ServletServerHttpResponse(servletResponse);
	response.setStatusCode(clientResponse.statusCode());
	response.getHeaders().addAll(this.httpHeadersFilter.filterHeaders(clientResponse.headers().asHttpHeaders()));
	OutputStream responseBody = response.getBody();
	response.flush();

	return clientResponse.body(BodyExtractors.toDataBuffers()).window(1)
