[undertow-dev] undertow http client - howto long polling xhr?

Hi, I'd like to build an HTTP client that receives chunks of data as part of a long polling HTTP request, using Undertow's HTTP client. So in a way, I'd need callback methods like "onHeader" and "onContent". the http client is parsing the *whole* HTTP response and does not provide those callbacks. Is there a way to achieve this? If not, does this qualify as an interesting feature for undertow's HTTP client? Thanks, -- Brian Clozel
