Multi-part Request body is not kept after 307 Redirects

[prabhash1785]

In my current usage of async-http-client, I notice that multi-part request body is not kept after server sends a 307 redirect for HTTP Post. It does keep request body for non-multi part data though.

We are using Async Http Client lib Version: 2.2.0

Multi Part Request data is:
Part 1: jsonpart string
Part 2: byte array of mime data

Multi-part data is set as follows:

Request request = new RequestBuilder(Methods.POST)
                       .addBodyPart(jsonPart)
                       .addBodyPart(mimePart)

Looking at this code, I don't see 307Interceptor is setting MultiPart data. I am hoping I am looking at the right place.

async-http-client/client/src/main/java/org/asynchttpclient/netty/handler/intercept/Redirect30xInterceptor.java

Lines 102 to 114 in 6e4c1a6

	if (keepBody) {
	requestBuilder.setCharset(request.getCharset());
	if (isNonEmpty(request.getFormParams()))
	requestBuilder.setFormParams(request.getFormParams());
	else if (request.getStringData() != null)
	requestBuilder.setBody(request.getStringData());
	else if (request.getByteData() != null)
	requestBuilder.setBody(request.getByteData());
	else if (request.getByteBufferData() != null)
	requestBuilder.setBody(request.getByteBufferData());
	else if (request.getBodyGenerator() != null)
	requestBuilder.setBody(request.getBodyGenerator());
	}
